One grain of sand don't make a desert   A drop in the ocean is too hard to measure   One little lie doesn't mean you're a liar   One puff of smoke doesn't mean there's a fire      So how could a mountain of love disappear?   A little bit there, a little bit here      Oh, one thing led to another   One night at a time, we lost each other   You're workin' late, she called again   A couple of drinks, she's just your friend   What's the harm? Oh, one thing led to another's arms      You'd fall into bed, too tired to hold me   A couple of rumors, some nobody told me   The first time your touch was just not the same   The night you blew up when I said her name      I closed my eyes to the tears on my face   But finally the pieces just fell into place      Oh, one thing led to another   One night at a time, we lost each other   You're workin' late, he called again   A couple of drinks, he's just my friend   What's the harm? Oh, one thing led to another's arms   Oh, one thing led to another's arms
