From Summer Activities for Children, Part 2:
Go to the park or some other place where children play. Talk with your child about how other children you see there might be feeling. If any of them are sad, talk with your child about how to make them feel better.
For example, if a child falls down, your child could offer a bandage. If a child is sad that he has no playmate, your child could offer to play. If a child is upset that he sees others having snacks and he has none, your child could offer to share.
