I've just read a news story about a seven year old boy in Australia who broke into a zoo and fed several rare animals to a crocodile, battering some to death first. No one knows why he did it. Sounds like a modern myth, but got me thinking:
What inexplicable bad deeds did you do as a child and can you now understand why you did it?
I remember repeatedly pushing my tricycle, when I was about six, into a window until it smashed. I'm not sure why I did it but it was something to do with wanting to see what would happen. I, of course, pretended it had been an accident.
