You summed up my interpretation and reaction to the song prior to watching the video. In particular I hated the song’s sidewalk metaphor, which is a poor one for describing an abusive adult relationship. I listed the song in the thread Song Lyrics that just annoy you.
But I’ll admit, I changed my tune (pun intended) after watching the video. Maybe it’s because I derided it so often that when the video clarified it’s about a parent/child relationship, the pendulum swung back so hard it actually moved me to tears (as I mentioned in the Entertainments that are guaranteed to make you cry thread.)
It was victim-y when I thought as an adult she hooked up with a loser (her choice). But a child has no choice of her parents. The video hit a nerve with me. Yes, adults need to get over their troublesome childhoods (I like to think I have). I am nonetheless moved by a piece of art that lets me reflect on how such a childhood feels and how much it sucks.
