'is it normal that i'm getting annoyed by my best friend?'

Well try speak to her. I'm fighting with my friend at the moment and her telling me there was a problem made me realize there was a problem. Things are getting better slowly. If you still want to be friends you need to sit her down and tell her how you feel.
Good luck

Headbutt her, tell her to fuck off, then start kissing her from the neck downwards.

she a ho

be "busy" alot

Send that tramp's call straight to vm

Shes a bitch, quit hanging out with her.

she might be jello...my friend did that to me then i stopped talking to her, after a couple weeks she told me why she was doing it..were still bestfriends =]

I had the same problem I just slowly stopped hanging out with her until we naturally grew more distant

Yep, just like the above poster said. Be busy alot. I've done it. Even if you are watching tv. You are busy watching tv.
