The document is about a group of children at School No. 17 in Koszalin, Poland. They initially exclude a new shy boy from their games. However, one child points out they have never asked him to play and should be more inclusive. The children realize being kind to others and having friends to talk to and play with can help overcome sadness, fears, and problems. They decide to ask the boy to play with them and will support each other going forward.
