I used to jump on my bed when i was a kid but would get into trouble. In the end it did break!

Never had water fights or anything. I was an only child so mostly played by myself.

Wasn't allowed off school unless i was sick or very tired, as i was anaemic for a while there.

I don't think i will allow that stuff. Except for the days off school if they are tired/sick. Water fights would just get too messy with the amount of furniture we have.
