My Mom is convinced that having ushers is just tacky and rude, because they're dressed up as though they're in the BP, but not actually standing at the altar. She asked a few months how we were going to involve my brother in the wedding. I said, "We're going to have him be an usher." She thought that meant "groomsman." Then she got all pissy with me when I explained to her that ushers don't actually stand up at the altar, they assist the guests with seating, hand out programs, etc.
Since then, whenever I've seen or spoken to her, my mother's demeanor towards me has been very cold. She constantly says things to me like "Now you have to write thank you notes, because you're receiving gifts." and "you have to thank your shower hosts." and just reminding me about all of these things that are completely common sense, because apparently since I'm committing the "faux pas" of having an usher, (actually, 2 ushers.... one of FI's other friends is going to be an usher as well) I must not know anything else about wedding etiquette. And she does it in this condescending, curt way that just makes me want to smack her. (Sorry, just venting... I would never actually smack my mother. I love her, I swear, she's just making me nuts! A good gif might be very satisfying though!)
So anyway, my question is: is it really a new thing to have Ushers who are not groomsmen, so my Mom just honestly wouldn't have known that this is something people do? Am I being rude to have my brother be an Usher? If I am, then, please correct me on that. He and I aren't close at all, and neither are he and FI, but FI and I did have him over and talk to him about what he would feel comfortable doing. He said being an usher sounds fine to him, but my Mom, and actually, now that I think about it, my step-dad as well, are treating me as though I'm this horrible jerk for not having my brother up at the altar with us.
