We are a small group of friends who go out for dinner together every 2-3 months or so. It's just three couples so a small group. Anyway, one of them couldn't make the scheduled dinner so we have decided to invite the rest to our house for a dinner party. We put a lot of time, money and effort to get the best food, cook all three courses from scratch, get expensive wines etc... it was a lot of money and work. I thought it went well, everyone was laughing and the food was good. Although one of them was still very hangover from a couple of days earlier and one was very tired from traveling for work..I understand this and any occasional yawns because people are tired from work and having kids. But aibu to be really upset about not having received even one text today to thank us for the evening? They obviously all said thank you as they left last night but the silence today felt a bit deafening. If we ever happen to go to theirs for a party, we always make sure to send a thank you text the day after and so does everyone else. Am I being unreasonable to feel quite upset about receiving nothing at all? Is it normal?
