The airport was full of people and sounds. Peter walked with his bags near the gates.

A little girl looked scared and stood alone. Peter saw her and asked, "Are you okay?"

She said, "I lost my mother."

Peter held her hand and said, "Let's find her together."

They went to the help desk, and soon her mother came. The girl smiled and hugged Peter.

"Thank you," the mother said.

Peter felt good inside.
