I invited a couple of friends over for dinner and went to lots of trouble shopping for, and cooking a nice meal. When they arrived one of them announced that she'd eaten with the children at tea time so would only have a tiny amount of dinner. This happened to me before when I had a few people over for a meal and one of them announced that she'd had a dinner at lunchtime and would just have the starter.
(and before anyone asks, no I'm not a crap cook)..
Other friends have had similar experiences. AIBU to think people like this are a bit rude and inconsiderate?
