I get the whole "there are no duity's of a BM or a MOH". HOWEVER.... I think when most people agree to be a BM in a wedding, they expect to chip in/help plan a bridal shower, the bach party, the dress, etc. I know when I agree to be a BM those are things that the bride is probably expecting me to do. Why is it any different if I'm the bride?
My MOH didn't plan the bach party, a few of my BM are, and I know my MOH can't come, and that's fine... but I was a little disappointed at first, because I thought she would be there...
I get demanding things from friends/relatives is not the way to do things, but lets be honest here, if all my BM's (friends) were like we aren't doing any of this stuff, tough... when I did it for a few of them already, I would be hurt and disappointed. Would I demand it of them, no... but I think generally, it is expected.
When girls come on here upset that their BM's or MOH is basically blowing off everything, they have every right to be hurt by it. I'm not saying demand things, but it's upsetting when you yourself do things, and it isn't returned.
I'm lucky to have friends/family who respond to e mails, and are happy to pick out their BM dresses... but if I didn't, I gotta say, I'd be disappointed that they were doing nothing.
