So I only have one sibling, a younger sister. She definitely expects to be my MOH, saying that since she's my only sister she has to be. The problem is that while I love her and we are pretty close, she is the most irresponsible person ever.
I would rather ask one of my friends (whom I've only known for about three or four years) instead. Is that terrible of me? I know I don't have to pick my sister just because she's my sister but I know she will be really hurt. On the other hand, I don't want her performing traditional MOH duties but I would feel uncomfortable letting her have the title and asking someone else to do the work.
Any advice?
