DS has been invited to a birthday activity from a boy in his class. I confirmed the invitation with the parent but then she asked for a certain amount of money for the activity. I thought this was odd but as it was a small amount, I paid. But I knew the children were going out for dinner after the activity- so just in case, I asked the parent if parents have to pay for the children's meal. She said "Yes". I had to pay for the activity, the birthday present and now the food?!! AIBU to let DS miss the birthday activity and skip the food. I don't enough funds to do the birthday food AND the birthday present. AIBU?
