I don't really like my best friend.
What about your best friend don't you like?
I get tired of status updates he makes, he's a bitch and I think we should stop being friends.
Status updates are a silly thing to break up over and best friends should like each other enough to see past small issues. If you break up with friends over small problems you'll end up without any friends.
Why? I don't care about my friend's facebook posts.
I guess I'm saying that if you keep leaving friends over small issues then you will be alone because sooner or later, people will make you angry. No one is perfect including yourself, so you need to get over petty issues you have with others.
