I don't know what his life situation is that he is trying to sell all these items on the side of the road. I don't know if he had to pry these toys from his children's hands and walk out the door as they cried. I don't know if he's selling his only can of shaving cream so he can buy food. I don't know if he has any support or help to make it through whatever crisis he may be experiencing.
Challenge your child to think of anyone they could share something with who may have less in some way than them. Maybe they can help an older neighbor bag a bag of leaves, or pick out some new toys to buy for Cook Children's Hospital, make some food or a card for a friend who has been sick or make a bag of goodies to hand someone who is experiencing homelessness.
