Ships that pass in the night...

Two verses i came across which use a phrase which i like a lot...but in very different meanings...
==============================================
“Ships that pass in the night, and speak each other in passing,
Only a signal shown, and a distant voice in the darkness;
So on the ocean of life, we pass and speak one another,
Only a look and a voice, then darkness again and a silence”
- Henry Longfellow (This is the poem where the phrase originated)
==============================================
“There are those who pass like ships in the night,
Who meet for a moment, then sail out of sight
With never a backward glance of regret;
folks we know briefly then quickly forget.
Then there are friends who sail together,
through quiet waters and stormy weather,
helping each other though joy and through strife.
And they are the kind who give meaning to life.”
