Peter later meets a little girl named Maimie Mannering, who is lost in the Gardens. He and Maimie become fast friends, and little Peter asks her to marry him. Maimie is going to stay with him, but realises that her mother must be missing her dreadfully, so she leaves Peter to return home. Maimie does not forget Peter, however, and when she is older, she makes presents and letters for him. She even gives him an imaginary goat which he rides around every night. Maimie is the literary predecessor to the character Wendy Darling in Barrie's later Peter and Wendy story.
Throughout the novel, Peter misunderstands simple things like children's games. He does not know what a pram is, mistaking it for an animal, and he becomes extremely attached to a boy's lost kite. It is only when Maimie tells him that he discovers he plays all his games incorrectly. When Peter is not playing, he likes to make graves for the children who get lost at night, burying them with little headstones in the Gardens.
