I'm going to end an 11 year long friendship over work politics
What about this friend makes you want to end the friendship?
Haha, she's such a bitch and I can no longer tolerate her presence!
It seems like a bad idea to lose an 11 year long friendship over a disagreement about work. When you're friends with someone for that long you should try to work out your differences before ending the friendship.
Haha, we're not true friends since she is so mean to me. I need someone who likes me for who I am.
If it has truly been eleven years, then I think you're overestimating how strong your bond is and you should try speaking with her about it before ending anything. It's healthier to keep long friendships than get rid of them.
