"It's about that point where you don't feel anything—you don't feel happy, you don't feel sad but you want to feel something. It's a situation I was in and I think everyone's been in. There's always someone in a relationship who wants more attention and starts trying too hard to please the other person. The thing is, the more you try to please that person, the less effort they make because they know you'll do anything they want. It's that stage I'm singing about on 'One'."
