Terrible things you've done to your siblings

[NajdorfDefense]

My sister and I used to fight all the time, mostly verbal. She's years older than me, and one time when I was 9 she was sleeping and I managed to push a bookcase over to fall on top of her.

She got revenge later by taking all of my baseball, football, basketball cards out of their boxes and throwing them in a pile on my floor. I come home from school and there was like 40k cards in a pile in my room. Good times!
