First of all,I just want to clarify that this user isn't a bot,my name is so random because I know this person uses Reddit and goes on r/AITA so I don't want him to see this and have trouble at school tomorrow.Kay,now for the story.

I am 12yr male and I'm currently in 6th grade.I had been friends with this person since 3rd grade.Since we have gone to middle school I have met a new friend,well call him B.my old friend well call him A, has been really mean to B ever since I met him.

For X-mas I got a Nintendo switch and ssbu.A has asked to come over to play.I said no since he has been mean to B.AITA here?
