....instead of offering to help out!
It's not only about the child being able to cope without the parent. I do expect 11 year olds to be ok without the parents but how can it not occur to mums and dads that I may struggle to feed and look after a bunch of 15 kids when they sit down for food and cake?
I find it very rude that the parents just shoot off without even asking if I might need help. AIBU?
