I think I'm going to make my friend hate me.
Why would you want your friend to hate you?
I will talk about my friend behind her back because it is fun
You need to be more respectful of your friend or she will not be available for you when you need her. You are being rude and neglectful to those are supposed to be important to you.
Yea, maybe? I'm not sure.
All I'm saying is that if she is your friend then you should be nicer to her.
