Ohhhhh fuck. You fucked up. You kind of, well... stole a time machine. And you went back to the 1950s. And then, like... the time machine disappeared. So now you're stuck in the 1950s. SHIIIIIIIIT.
You're FAIRLY sure — like, 75% sure — the time machine is gonna come back for you. Eventually. In the meantime, though, you've gotta blend in to 1950s culture WITHOUT doing anything that will fuck up the timeline when you go back to the future. BE VERY CAREFUL.
