It isn't often that things go well for Derpy. Between her eyes, her clumsiness, and her propensity for disaster, it's hard enough just to make friends. Add to that a revolving door of jobs and a daughter to raise, it's a miracle that she has much time for herself at all. So when her date stands her up at a loud, flashy club, it hurts.
Maybe she should just give up. Or, maybe she just needs the kindness of a strange bartender in purple shades.
