Because I'll Forget Everything

My job is mostly at night, which means I'm constantly fighting sleepiness every day. The girlfriend waving at me from the sidelines of a buffet, the email that said *"I'll break all your joints,"* the old friend I was with while "waiting to be punched" by a coworker... We all eventually forget everything, good and bad. That's why I'm writing about the things I didn't want to forget.
