Is it normal my brother and i broke each other's belongings 1 by 1?

This was a few years ago. My brother and I had a fist fight (again) and our dad broke it up before we had satisfactorily pummeled each other.

I forget who started this part, but since the fight wasn't properly settled one of us went in the other's room and broke one item. Then again, and again, and again. One item per day and we never caught each other in the act either. We'd go to our rooms at some point in the day and there was the inevitable one broken belonging.

The only thing I specifically remember breaking of his was his Bo Jackson poster, I ripped Bo's face out of it. The only thing I definitely remember of mine that he broke was this decorative porcelain box, I found it crushed beneath my bedpost. I wish I could remember more stuff because it seems so funny now.

This went on every day for about 2 weeks.

Is this normal? Did you ever do this with your sibling?
