Clever kids prefer adult company
But that was never me
I would dance like there was no-one watching
I would dance like I was loveless and proud
Equals's official lyric explanation
It’s another reference to youthful idealism, basically. So that when you’re young you can dancelike no one’s watching - so you don’t care what people think of you, you don’t care that no one loves you. You’re proud of who you are anyway.
So, it’s that kind of… yeah, it’s a comment on the purity of youth, I guess, compared to the cynicism of adult life.
