Lyric discussion by Caleddin 

Cover art for Alleged lyrics by Beta Band, The

As it eerily often happens with the Beta Band, this song reflects something I've gone through nearly perfectly despite confusing lyrics. You date a girl, she jokes about how you'll never stay together. Then, much later, she disappears from your life for some spaced reason, and you try to remember it fondly by thinking of the jokes but all that really does is hurt ya more, or make you want to hurt yourself. And the fuel to harm yourself with your memories is all the little jokes that hurt so badly in retrospect.

The last bit, I assume, is representative of your overworking mind, just repeating unknown questions.
