yes, it is rude but it always happens. I am guessing it does anyway. For us, it was the cousin who brought 7 people (2 were invited) and then gave us $10...but their daughter is getting married in May, so we will send them their card and $10...but don't plan to make the 6 hour drive to attend. They were also the guests who showed up 1 hour early which meant we couldn't do any of our preceremony formal pictures either. Then, when it took about an hour after ceremony to get them done...so we let everyone start eating ahead of when we came down to the reception so they'd be more comfortable, they are also the guests that complained because it took too long fo rour pictures AND because they didn't know every guest there!! They comprised 1/4 of the guests, and yes, todd had 3 couples from his work there and I had 1 friend from previous place I lived plus my mom, brother, his GF and my kids...but come on people...this wedding was about us, NOT you...
We won't say anything and it sure didn't bother us at all during wedding/reception, and frankly, really doesn't bother us now. But the lack of manners, etiquette or even class is noticeable... :) It would hurt our feelings much more if it were a close friend or relative, though.
DH's parents really made up for that, though. As a surprise, they paid for the entire rehearsal dinner...we had definitely not planned on that as it was our 2d wedding, but it was super sweet of them PLUS they gave us a card and cash for honeymoon. AND on top of it all, Dh's mom's mom (his grandma) passed away the day of the rehearsal (she had alzheimers) and they didn't say one word about it to me, not anyone, until after the wedding and assured DH taht they definitely did NOT want him to postpone anything.
they are truly amazing, kind, generous, fun, terriffic parents in law...and I am very, very happy to now be an official member of their family.
after reading some of these, I guess for the most part our guests were pretty great.
