For me it was curiosity.
When I was three, every night on the news, I would see the reports of the Vietnam war, with army people loading their dead and wounded into helicopters. One day I saw a couple of those same type of military helicopters flying over the mountain behind my house. I wanted to visit the army people and ask them questions, so I climbed the mountain. I made it to the top of the mountain (about 700 feet up and a mile away). I could see my house below me on one side, and wilderness on the other. I did not see the helicopters in the wilderness valley. I was thirsty, hungry and disappointed. I went home and no one ever noticed I had been missing.
A couple of weeks later, my mother left us with a friend in the city, while she went to take care of adult things. I was playing in the backyard, and I kept seeing military helicopters fly over. They were going lower and lower like they were landing. (Later I found out there was a marine base nearby). I escaped the yard, and wandered down the street on my tricycle. I was picked up by the police, two miles from my babysitters house. I was very close to the base. I refused to talk to anyone at the police station. Several hours later, my mother returned to discover me missing. She called the police and we were soon reunited. The police accused my mother of neglect and abandonment, but found out it was the three babysitters watching us kids that failed.
I was watched very carefully after that. Most people were afraid to babysit me. Besides wandering off, I was notorious for asking questions. Babysitters claimed my questions made them feel foolish or uneducated. I still love to travel and discover new places.
