Two Ships
It's strange, the things you come upon, when you least expect to....

Ships that pass in the night, and speak each other in passing,
Only a signal shown and distant voice in the darkness;
So the ocean of life, we pass and speak one another,
Only a look and a voice, then darkness again and silence.

Henry Wadsworth Longfellow,
Tales of a Wayside Inn, Part III,
The Theologian's Tale, 1873
