• Janet Jackson discussed this song on her record label's website: "The ambivalence and the discipline are in conflict. I can relate to the story. In fact, I can imagine myself in the story. After a long relationship that ends in pain, I turn to my old friend, discipline. I discipline myself not to get involved, not to be vulnerable, not to fall in love. My discipline protects me from any more hurt. My discipline keeps me on track. But here comes someone who's so real and right that, as the song says, 'This can't be good.' So discipline really isn't discipline. It's just self-protection and fear of being hurt. It's resistance. Thankfully, the heat of pure passion melts the resistance. And the result is free-flowing love."
