Time

Tired of lying in the sunshine
Staying home to watch the rain
And you are young and life is long
And there is time to kill today
And then one day you find
Ten years have got behind you
No one told you when to run
You missed the starting gun

And you run and you run
To catch up with the sun, but it's sinking
Racing around to come up behind you again
The sun is the same in a relative way, but you're older
Shorter of breath, and one day closer to death

Every year is getting shorter
Never seem to find the time...
