My sister is supposed to be my MOH. The problem is her and I do not get along very well, we are 7 years apart in age and have really nothing in common. The only time I really talk to her is when I am home from college and she happens to be at my parents' house. I know I should just keep her as my MOH because she is my sister but I'd rather have my best friend as MOH. What should I do? Anyone else have this problem?
