i and one of my very good friends had a fight 2 years ago about a very stupid matter.we stopped talking to eachother. thn she immigrated to UAE after 2 month without telling us (old friends) but her new friends knew that. (we were science student but she was commerce). then i heard that she used to call many ppl but she never called me or my another good friend. now today she added me on MSN and Facebook. now what should i do?
