I was on the platform, plugged in to music, listening to Matt Sever's Songs My Mom Doesn't Like. It's a great EP, with covers of Danzig's Mother and a campfire singalong called "Black Blackness" which discusses the hole in his soul. I was humming quietly to myself, waiting for my train, when the last song came on. I got kind of into it I guess, because when the chorus came on I forgot myself and sang out, really loud, "Jack you off!!!"
Then I realized that I had actually sung it out loud, and looked around in a panic.
For once, I was happy that no one understood me.
