Some theorists suggested that it was the result of substance abuse by the parents, which is why we saw it more in abandoned and unwanted children. Some doctors believed that hyperactivity was the result of the body's failure to produce certain key enzymes in response to physical stimulation; therefore the child needed to overstimulate himself in order to produce an equivalent amount of calming. Still others postulated that there was an emotional component to the disorder; that it was a response to a lack of nurturing. Most interesting of all to me was the offhand note in one article that some theorists believed that many cases of ADD were actually misdiagnoses. If you were unattached and didn't know who you were or where you had come from or where you were going, you'd have a lot to worry about; your attention might be distracted too.

Or… what if the behavior that was judged abnormal for Earth children was perfectly normal for Martian children? What if there was no such thing as ADD… in Martians?

At this point, I'd reached the limits of my ability to research the question. Who could I tell? Who would have the resources to pursue this further? And who would take me seriously?

Suppose I picked up the Los Angeles Times tomorrow and saw that Ben Bova had called a press conference to announce that he'd been kidnapped by aliens and taken into space where they'd performed bizarre sexual experiments on him… would I believe him? Ben is one of the most believable men in the world. Once, he almost talked me into voting for Ronald Reagan. But if I saw a report like that in the newspaper, the first thing I'd do would be to call Barbara and ask if Ben were all right.

In other words… there was simply no way for me to research this question without destroying all of my credibility as a writer.

Even worse, there was no way to research it without also destroying my credibility as a parent.

Up until this time, I'd always been candid with the caseworkers and therapists; I'd talked to them about our discipline problems, about my feelings of frustration, about ever little step in the right direction and every major victory. But… suddenly, I realized this was something I couldn't talk to them about. Suppose I called Kathy Bright. What could I say? "Uh, Kathy, it's David. I want to talk to you about Dennis. You know how he says he's a Martian? Well, I think he might really be a Martian and…"

Uh-huh.

If the adoptive father was starting to have hallucinations about the child, how long would the Department of Children's Services leave the child in that placement? About twenty minutes, I figured. About as long as it took to get out there and pick him up. She'd pull him out of my house so fast they'd be hearing sonic booms in Malibu. And I wouldn't even be able to argue. She'd be right to do so. A child needs a stable and nurturing environment. How stable and nurturing would it be for him to be living with an adult who suspects he's from another planet and is wondering about his ultimate motives.

If I pursued this, I'd lose my son.

The thought was intolerable. I might never recover. I was sure that he wouldn't. For the first time in his life, he'd finally formed an attachment. What would it do to him to have it broken so abruptly? It would truly destroy his ability to trust any other human being.

I couldn't do that to him. I couldn't do anything that might hurt him.

And what about me? I had my own "attachment issues." I couldn't stand the thought of another failure. Another brick in the wall, as they say.

That was where I stayed stuck for the longest time. I walked around the house in physical pain for three weeks. My chest hurt. My head hurt. My legs hurt. My back hurt. My eyes hurt. My throat hurt. The only part of me that didn't hurt was my brain. That was so numb, I couldn't think.

I didn't know if he was a Martian or not. But something weird was going on. Wasn't it? And if it was just me — if I was going insane — then what right do I have to try to parent this child anyway? Either way I lose. If he's a Martian, I can't tell anyone. And if he isn't a Martian, then I'm going crazy.

I started looking for local evidence. I began browsing through my journal. I'd been making daily notes of interesting incidents, in case I ever wanted to write a book about our experiences. At first, I couldn't find anything. Most of the incidents I'd written about were fairly mundane. Not even good Readers' Digest material.

For instance, the week after he moved in, I'd taken him to the baseball game at Dodger Stadium. For the first part of the game, he'd been more interested in having a pennant and getting some cotton candy than in what was going on down on the stadium floor. But along about the fifth inning, he'd climbed up onto my lap and I began explaining the game to him. "See that man at home plate, holding the bat. Wish for him to hit the ball right out of the park."

"Okay," said Dennis.

Cra-a-ack! The ball went sailing straight out into the right field stands. Someone in the lower deck caught it and the runner sauntered easily around the bases while the organist played, "Glory, glory, Hallelujah."

"You're a good wisher, Dennis. That was terrific. Want to try it again?"

"No."

"Okay."

Two innings later, the Dodgers were one run behind. I asked Dennis to wish for hits again. Four pitches later, there were runners at first and third.

It didn't matter to me who came up to bat now; I hadn't remembered the names of any ballplayers since Roy Campanella was catching for Don Drysdale and Sandy Koufax. As far as I was concerned, Who was on first, What was on second, and I Don't Know still played third. I liked baseball only so long as I didn't have to be an expert; but I'd never seen the Dodgers win a game. Every time I came to the stadium they lost; so I'd made it a point to stay away from Dodger Stadium to give them a fair chance at winning. I didn't expect them to win tonight; but Dennis's wishes had brought them from three runs behind.

"Okay, Dennis," I said, giving him a little squeeze. "It's time for one last wish. See that guy at the home plate, holding the bat. You gotta wish for him to hit a home run. All the way out of the park. Just like before. Okay?"

"Okay."

And just like before — cra-a-ack — the ball went sailing deep into right field, triggering a sudden cluster of excited fans scrambling down across the seats.

The Dodgers won that night. All the way home, I kept praising Dennis for his excellent wishing.

A couple of weeks after that, we were stopped at a light, waiting for it to change. It was one of those intersections that existed slightly sideways to reality. Whenever you stopped there, time slowed down to a crawl. Without even thinking, I said, "Dennis, wish for the light to turn green please."

"Okay," he said.

— and abruptly the light turned green. I frowned. It seemed to me the cycle hadn't quite completed.

Nah. I must have been daydreaming. I eased the car through the intersection. A moment later, we got caught at the next red light. I said a word.

"Why'd you say that?"

"These lights are supposed to be synchronized," I said. "So you only get green ones. We must be out of synch. Why don't you wish for this light to change too please."

"Okay."

— green.

"Boy! You are really a good wisher."

"Thank you."

A minute later, I said, "Can you wish this light to turn green too?"

"No," he said, abruptly angry. "You're going to use up all my wishes."

"Huh?" I looked over at him.

"I only have so many wishes and you're going to use them all up on stoplights." There was a hurt quality in his voice.

I pulled the car over to the side of the road and stopped. I turned to him and put my hand gently on his shoulder. "Oh, sweetheart. I don't know who told you that, but that's not so. The wish bag is bottomless. You can have as many wishes as you want."
