My BF is getting married in December. Her wedding was originally supposed to be in May but she and her FI decided to move it up 5 months. I can't actually be at her wedding now so I'm trying to make it a really big deal before the hand. I'm throwing her and her FI a coed wedding shower (he wanted to be involved too). Everything had to be done quickly, so it was a little bit spur of the moment, but invitations were in the mail 3 1/2 weeks in advance. I've enlisted the help of some of our friends and the party is at the end of the week. Everyone I talked to (especially the bride!) is really excited about it. That being said, my friend's FI is in a band and he found out today that he has band practice on the same day as the shower and the times overlap. The person who called the band practice was invited to the shower. In fact, his wife is even helping me host it. Also, the practice affects several of the people who would attend/help with the shower. I wanted this to be a fun, special time for my BF and her FI, and now she is really upset about the whole thing. She is also taking a lot of crap fromm a few people who think she is overreacting. I feel like the band leader should have been a little more considerate, but I don't really know what I can do now. Any advice or suggestions on how to handle this situation? Is the bride overreacting or is she justified in being upset?
