CIRCLE
Harry Chapin

All my life's a circle, sunrise and sundown.
The moon rose through the nighttime till the daybreak rolls around.
All my life's a circle, but I can't tell you why.
The season's spinning round again. The years keep rolling by.

Seems like I've been here before. I can't remember when,
But I've got this funny feeling that we'll all get together again.
There's no straight lines make up my life. All the roads have bends.
There's no clear-cut beginning, and sometimes no clear end.

I've found you a thousand times. I guess you've done the same;
But then we lose each other. It's just like a children's game;
But as I find you here again, the thought rolls through my mind:
Our love is like a circle. Let's go 'round one more time.
