You have ever done to a sibling?
When I was about 8 I guess and my sister was 5. We were playing in the park and I noticed a huge pile of dog crap. She always had to be the "princess" when we played. So I unwillingly agreed again that I would be the wicked "whatever". We didn't have shoes on and I told her that she was the princess and I was kidnapping her and she had to close her eyes and I walked her right through the pile.
She cried, I laughed all the way home and then got in trouble.
We were talking about it the other day- she is still bitter and I was lmao.
