The female singer on the track (I don't have a name for her - maybe someone can help here?) suggests that he will have his fun and then leave her:
Her: After a while you'll forget everything.
It was a brief interlude and a midsummer night's fling,
And you'll see that it's time to move on
Him: I won't do that! No, I won't do that!
Her: I know the territory, I've been around.
It'll all turn to dust and we'll all fall down,
And sooner or later, you'll be screwing around.
Him: I won't do that! No, I won't do that!
So now you know.
