I just introduced my four bridesmaids to each other via email on Sunday (6/12). My MOHs are college friends and sorority sisters and the other two are hometown friends that I have known from middle school and high school. The girls live in two different cities and will probably not meet each other face to face until the wedding (next year). Yesterday one bridesmaid, HS friend, sent an email detailing her experiencing trying on the bridesmaids dresses to the girls and she was apparently slightly abrasive. According to my MOH, this bridesmaid was shooting down all of her ideas and being rude. It seems like my friend from HS is trying to prove that she "knows me better" and blah blah blah.
What should I do to avoid the ego trip and competition that I feel is coming between them?
