I was at a Saturday afternoon matinee of The Nutcracker Suite at the weekend. The place was hopping with excited little girls and delighted grannies bringing them for an afternoon out etc. During the performance there was no unreasonable noise but you could hear a couple of little girls in the row behind me occasionally whispering "we do that at our ballet class", or "why are they dancing in a forest" and some kids rustling sweet papers, adults giving explanations in low voices and so on. A couple of ladies in the seats behind me kept looking backwards in annoyance and one of them said "shhh" at one stage.
AIBU to think if you want a quiet grown up performance you don't choose the Saturday afternoon matinee? In the same way that if you want your children to be able to make a little bit of noise you don't bring them to an evening performance?
