My fiance had 4 GM picked out, but I only have 3 BM, so he decided to "demote" (his words not mine) his brother that he's not that close to anyway, to an usher. I feel bad because if I only had another person that I could ask to be a BM, I would. Should I let him "demote" his brother or try ask someone else to be a BM?
Also, what's the role of an usher? I know they seat people, but are they included in pictures and do they sit at the head table?
