My friend and her husband had a family emergency. So they had to go help out their family who are 40 miles away. The first night of the emergency they left their 2 toddlers with us and I was okay with that. I dropped them off to their school which is quite far from our house and picked them up. But the parents said they would need us to keep their kids almost for the whole week! I understand they have an emergency but since they are only 40 miles away, I would think one of the parents would be back to take care of the kids? I have a toddler myself and I am totally overwhelmed with everything. Am I petty in feeling resentful?
