My soon to be sister-in-law is going to be a bridesmaid at my wedding, however I just found out that she is not going to attend the reception because she doesn't like drinking or smoking (which I completely understand), but I don't know if i should keep her in the wedding because the duties of a bridesmaid doesn't end with just the wedding....and I think it's kinda rude to be in the wedding but not show up for the reception. what should I do? Replace her and find someone that will go to the reception or just leave it alone?
