Since the beginning of the year she always gives me death glares in class and attitude when she's talking to me. I don't think I've ever done anything to upset her so why would she act this way? She gets along with all the other girls in class besides me. Like for example I'll be talking to my friend and she will walk up to us and chats to her and gets on well with her and then when I try to join in she never looks at me in the face when I talk to her almost as if she hates seeing me. And She glares at me and when I'm talking to my friend, she won't join in the conversation she will just smirk which gets so annoying and I don't even know what I did to her?
