Cover art for My Town lyrics by Armor for Sleep

I think this song is about an outcast or black sheep type character ("Scare kids away", "Houses shut their lights as I pass") who has finally had enough of this place ("This is the end of rotting away", "This is the end of keeping it in") and is either leaving or has made a decision to stop caring that people don't like him.

He also seems to enjoy toying with the townsfolk; running around scaring kids and falling asleep in the middle of the street (kind of reminds me of Sylvie from Marilynne Robinson's Housekeeping). Perhaps this is also a sign that he doesnt really care what people think of him.
