BeSt FrIeNdS

I don't know if its just me, but having a best friend is really     hard. When ever i want to eat lunch with an other group of people  one day, she will just automatically come with me, or if i want to be by my self she wont let me. People will automatically link her  to me, see us as a set. I have never been a person who likes to be defined and i fell as though because she is always around me that  may be happening. Now don't get me wrong, i love her and her       company but it seems like it should be OK to do things on our own  once in a while, right?
