Two friends that I want to be in my wedding party don't like each other. What should I do about them?
It's safe to assume that even if two people in your wedding party hate each other, they'll suck it up for you and deal with having to look at each other for just one day. Although they'd both be bridesmaids, it should be easy enough for them to ignore each other while keeping busy making sure that your wedding runs smoothly -- separate parts of it, of course. Just make sure each one has other friends to hang with so neither feels uncomfortable at the party.
