Cover art for Bathtub lyrics by Front Bottoms, The

He wants to change who he is and is trying too hard to do so (scrubbing his body til it bleeds, washing his hair with soap, running and even driving away from where he is now).

He's questioning if he can really become a different person, though. This girl he loves makes him feel like he isn't this great person he wants to be. Yet, it's not always so black and white. Maybe you can't or don't have to drop the bad parts of yourself when becoming who you want to be.

Kind of like his friend's mobster grandfather who is actually a really nice guy.
