My older sister is my matron of honor and i was her maid of honor when she was married......but i want my best friend to be my maid of honor and have them just share the role. I just dont think my sister is going to take that well. At some point i had already asked my best friend to fill the roll as maid of honor (after one to many cocktails , oops) So now i cant take it back and i dont want to....but how do i tell my sister without her being upset?
