The class starts in minutes. You're new at this type of thing. A crowd assembles at the door. Some of them seem to know each other. Wasn't this supposed to be a beginner's class? Why does everyone seem to be talking to each other like they already know what they're doing? Why does everyone have towels that match the color of their Lycra shorts? Why does anyone have a towel at all?
A young boy shows up and says hello to everyone. Oh Good God! It's the instructor. Like sacrificial lemmings, everyone follows him into the room. Shouldn't he still be in school? He looks too young to be in charge of his nighttime routine, let alone instructing a group of people he doesn't know.
You sidle shyly into the room. So that's what an indoor bike looks like! You hadn't been too sure right up to this point. You get on, surprised it doesn't fall over when you mount up.
Of course it doesn't, that's now how it works, it's got feet, you moron!
