Not sure why I've been thinking over these things this evening, but thought it'd be a good thread.
Stupid things I did as a child include...
1) 'Broadcasting' my own radio show about 'umbrella fun' when I was about six. By broadcasting, I mean standing in the front garden and shouting it at the top of my voice, all on my tod ? I did this for several evenings a week, all summer. People would yell at me from windows to shut up. How I filled this time with stuff to do with umbrellas, I'll never know.
2) I was very jealous of my older cousin. One day, she came over with some of those twee bath shapes full of liquid soap. I was feeling very malicious and decided to burst one when she wasn't looking. I decided to do this with my teeth. I ran all through the house, spitting bubble bath everywhere - hardly very inconspicuous!
3) My best friend and I once sat in a hedge for an afternoon and ate a pack of raw bacon that I'd stolen from the fridge.
