I'm not sure if this is a regional thing or not but I have never seen the groom's parents names on a formal wedding invitation if the bride's parents are hosting, paying, etc. Apparently, my fiance(who is from Indiana) parents were shocked, upset and then embarrassed that their names weren't mentioned with a "son of " line after his name. After hearing this I did some research and see that some sites list the groom's name as a wording option but i'm trying to figure out if this is a regional thing and that's why I didn't know about it. I do feel bad that their feelings were hurt but I honestly think they are making too big of a deal out of it.
Do you guys think I really screwed this up and should feel bad?
