How do I get closer to a friend who i have nothing in common with?

Don't sweat the little things in life. You are going to meet many phony people in your life. They usually act similar. Just let it go, and watch she does not cause problems behind your back. If you let every little things like that bother you in life, you will go crazy!!! Life is full of BS like that. Get used to it, and don't let it phase you!! Just don't return the feelings to her, if you don't want to be phony.
