When I was about 4 or 5, my brother Phil told me that our neighbor's new silver bullet shaped trailor
was really an alien spaceship and they had "taken" over our neighbors (ala Invaders From Mars). Of course I believed him. I always looked for the little hole on the back of their necks to see if the had been changed. They must have thought I was one wierd little kid, always trying to get behind them when they were talking to me.
