Someone is having a very bad day.
Her mom yelled at her for eating the last apple but she was so hungry and she bought that apple she's the only one in their little 'family' who keeps getting raises that keep up with the ridiculous prices, because she taught herself machines and electricity. A hundred million reichsmarks an hour how's that for money. But she might lose that job now too because there's no walkers to fix and the machine shop owner can't even buy parts and fuel and stuff anymore. She's no good at telling what he's thinking. He could fire her tomorrow, or just stop giving her raises. There was only one walker in the shop today at all, which doesn't bode well.
Her last letter from her dad was four months ago. It's getting increasingly hard to ignore the inevitable conclusion there. She always liked him more than her mom. Her red hair seems to make people dislike her. 'Not a real German'. She can avoid it, mostly, so far.
And she might be getting sick. That would practically be a death sentence, can't work if you're sick, can't rely on savings when they're worth half as much tomorrow.
She stumbles into a shop of some kind looking to spend her hundred million reichsmark bill on, perhaps, a loaf of stale bread or a few potatoes.
