My cousin will be a bridesmaid in my November wedding. She lives out of town and always stays with the family of an old high school friend of hers when she comes to visit. She recently emailed me and asked if I could invite the family she stays with when she's in town. We are already knocking people off the list in order to stay under a certain number. Considering I can't even remember their first names off the top of my head right now, my immediate answer is no. But is it rude of me to not invite them now that it's been requested?
