Met up with friends at the park this afternoon. Friends had brought bags stuffed with food - choc bars, crisps, fruit, babybels, biscuits... I had brought - nothing. We had had lunch and were going to have dinner, I was possibly going to buy them an ice cream as a special holiday treat, but aibu to not understand why children need to be constantly be fed little snacks all through the afternoon? They're not toddlers either, they're age five to eight.
