in high school, the girl who owns the locker next to mine keeps testing me. she always slams her door open into mine, blocking me or hitting my hand with the door if i'm still unlocking it. she also stands in front of my locker to open hers to get in my way.

my reaction is always "excuse me" to get her to move out of my way or i'll move her locker door when it's blocking mine.

what she does is subtle and i know that if i react angrily it will look bad on me, but i also feel like a pussy if i don't do anything.

what would you do?
