1. Having the bride's family pay for everything.
Weddings are really expensive - like, absurdly so - and for better or worse, they can be stretched out to include about a million events. So if a parent or a grandparent or a wacky aunt wants to help ease that financial burden, then by all means take them up on it and thank them profusely. Just don't expect it. Tradition dictates that the father of the bride is responsible for the engagement party, the invitations, the wedding dress, and the wedding reception (so, basically everything), but this, like many other wedding traditions, is uncomfortably reminiscent of the idea that brides are being "gifted" to grooms. And what happens when there are two wives? Pay for the wedding you can afford, accept help where you can, and take comfort in the fact that if you're paying the bills, you're in charge
