“I’m glad we found you,” said Bobby. “I’m glad you know the way.”

“That’s funny,” said Betty. “We lost the way and we found you. And you know the way.”

“Will you show us where Mother’s house is?” asked Bobby.

“To be sure, I will,” answered the policeman. “That is part of my business.”

“Do you do anything else?” asked Bobby.

“Oh, yes,” answered the policeman. “I walk up and down the streets and take care of the people.”

“Are you their father?” asked Betty. “Are you the father of all the people on the streets?”

“Hardly that,” answered the policeman.

“I know what you are,” said Bobby. “You are a big brother. You are a big brother to all of the people on the streets.”
