When I was a kid I was so afraid of adults that I used to run home from my friends houses whenever their fathers came home from work. I would watch for my friends to be outside before I went over to ask them to play for fear of their parents answering the door and having to talk to them. I can talk and make a fool of myself in front of kids, but if an adult enters the room I get all nervous and quiet.
And the sad thing: I realized that I'm still afraid of grown-ups, but now I am one. How's that for ironic?
