At the edge of the city park, a firefighter set down his heavy gear to rest.

His keys slipped from his pocket and fell through a narrow gap in the bench.

He tried to reach, but his hands were too big.

A little girl nearby saw him struggling.

"May I help?" she asked.

With a small hand, she slipped between the slats and pulled the keys free.

The firefighter smiled and tipped his helmet.

"Sometimes the smallest helpers make the biggest difference," he said.
