I once had a love, a true and lasting love   But the fool in me came out one night   And with her loving eyes   She saw right through my eyes   And she changed the night   I stepped across the line      I should have watched that first step   It was a mighty big step   When I started steppin' out of line   Though she's still lovin' me   It's not the way it used to be   That first step did something to her mind      I watched her slip away   A little more every day   And my conscience couldn't live with all that pain   She's growing colder   Since the day I told her   And the love we had will never be the same      I should have watched that first step   It was a mighty big step   When I started steppin' out of line   Though she's still lovin' me   It's not the way it used to be   That first step did something to her mind   That first step did something to her mind
