Why? Here there is no information about how severe the situation was or what was her reaction after telling this to the author. We also do not know whether she told this on purpose or not. More information is needed to determine who is at fault here.

New input: So some context. My school has a big field trip where they go to a big city. It is only for band choir or orchestra. Sorry for spelling and formatting. I'm on mobile. 

Up at my family's camper my brother kept using my earbuds and breaking them. He broke three fucking pairs.

My parents bought him two pairs of earbuds and I asked why he needs two pairs. He said that if one broke the othor will be useful. So my mom said to my brother that I was trying to steal a pair of his earbuds. I then stormed off. 

I was slightly angry that my brother got two pairs of earbuds after breaking three of mine. I was more angry that he got the earbuds for a stupid reason.

AITA for being angry at my brother for breaking my earbuds or is it just childish?
Solution:
not answerable
