This one is in the "ify" category. If it's not rude, it's darned close! The RUDEST dinner invite I've encountered though was when friends invited us for dinner at 8, along with our toddler, and knowing that the now-ex and I had to be at work at 5 a.m. the following morning. When we arrived, we were offered drinks...nice.......then after about 45 minutes of chatting, the woman excused herself to the kitchen, than called me in, and was pulling the meat out of the FREEZER, and wanted to know how long it would take to thaw!!! She than proceeded to send the guys to the store, to pick up veggies! Her husband was FURIOUS with her, and extremely embarrassed. Needless to say, dinners with that couple became meeting at restaurants!!!
