They passed each other at Gate 31, a little boy of eight with his parents and sister going in one direction, and a man of forty going in the other, looking for different gates to board different planes to different cities. 

The boy’s sister was dressed in little girl clothes and pulled behind her a tiny carryon that looked like a panda bear.

The little boy and the grown man walking toward him were wearing the same outfit: cargo shorts and shower shoes, T-shirts and baseball caps, backpacks and ear buds. 

They looked at each other in passing. The man quickened his pace, putting some distance between them. The boy turned and looked back over his shoulder, confused, as little boys often are by adults.
