Gravity lyrics

I left home when I was seventeen
I just grew tired of falling down
And I'm sure I was told
The allure of the road
Would be all I found
[ Lyrics from: http://www.lyricsmode.com/lyrics/a/alison_krauss/gravity.html ]
And all the answers that I started with
Turned out questions in the end
So years roll on by
And just like the sky
The road never ends

Chorus:
And the people who love me still ask me
When are you coming back to town
And I answer quite frankly
When they stop building roads
And all God needs is gravity to hold me down
