I was at an anniversary party last night. In the living area there was music and dancing, in the kitchen there was a gang of people (including me) sitting around chatting, drinking and having a laugh. In comes one of the fun police insisting we should 'join the party' - which we thought we were doing- and come into the sitting room and dance around the place with them. The reason we had chosen the kitchen in the first place was because we didn't want to dance and preferred to chat and joke and enjoy ourselves in our own way. She just wouldn't go away and everyone reluctantly trailed after her into the living area.
Its the same at weddings. These pests just won't let people sit back and watch the dancing or slip into the bar with a group of friends they want to have a catch up with.
Why can't people be left alone at parties to just enjoy themselves without knowing that any minute some jolly 'rocking around the Christmas tree' type is going to come up and start haranguing them and forcibly pulling them out onto the dance floor, or up to take part in the karaoke or do the conga.
AIBU to think these self styled 'life and soul of the party' types are a PITA?
