My Mama mapped out the road that she knows  Which hands you shake and which hands you hold  In my hand-me-down Mercury, ready to roll  She knew that I had to go  And hang out, make lots of noise  And lay out late with a boy  Make the mistakes that she made 'cause she knew all along    I was already gone  I was already gone  I was already gone  Life is a runaway train you can't wait to jump on    They say the first time won't ever last  But that didn't stop me the first time he laughed  All my friends tried to warn me the day that we met  "Girl, don't you lose your heart yet"  But his dark eyes dared me with danger  And sparks fly like flame to a paper  Fire in his touch burning me up, but still I held on  'Cause I was already gone  I was already gone  I was already gone  Life is a runaway train you can't wait to jump on    The last time I saw him, we packed up my things  And he smiled like the first time he told me his name  And we cried with each other  We split the blame for the parts that we couldn't change  Pictures, dishes and socks  It's our whole life down to one box   There he was waving goodbye on the front porch alone    But I was already gone  I was already gone  I was already gone  I was already gone  I was already gone  Hang out, make lots of noise  And lay out late with a boy  Make the mistakes that she made, life is a runaway train    My mama mapped out the road that she knows  Which hands to shake, which hands you hold  In my hand-me-down Mercury  Life is a runaway train you can't wait to jump on
