When the girl at the airport hears the announcement that her plane is starting to board, she turns to the boy who is seeing her off. "I guess this is goodbye," she says.
The noise of the traffic almost drowns out the sound of the word, but the shape of it lingers on the old man's lips. He tries to look vigorous and resourceful as he holds out his hand to the other old man. "Goodbye." This time they say it so nearly in unison that it makes them both smile.
It was a long while ago that the words God be with you disappeared into the word goodbye, but every now and again some trace of them still glimmers through.
