If you fool around on your boyfriend/girlfriend, chances are they’ll leave you, maybe even walk straight into the arms of your successor. And chances are you’ll see them together and it’ll be worse than anything you’ve experienced. Hey, it’s happened to many people. So that’s what this song is about. Our heroine walks by her ex’s apartment, only to see another woman silhouetted against the window. aaaarghh! Horrible. And she can’t walk away, she can’t even look away. She just has to stand there and watch….but eventually, much much later, she reflects that it was a good love she had, she threw it away for good, and that she;ll think twice next time. In fact, she’ll never do that again…
