Tim is a boy in your class who comes from a very poor family. The poor guy barely has money to buy food every day. In addition, all his colleagues laugh at him. But you watched him from a distance, although you never spoke to him. Today, you saw him in front of the vending machine counting his coins to buy a sandwich. But he didn't have enough. He looked sadly at the food in the vending machine and walked away. You bought a sandwich for him and caught up with Tim.
