I have descriptive fiction answers. They're still short and maybe a little flip, though!
1) Super no. No like crazy.
2) Weird, huh? Almost as though something were wrong with the world. I wonder what it is!
3) Keep everything from your old life that's part of you, like for instance the fact that you're a human being not a marmot, probably, and leave behind everything that was just part of your old life. Work out with the MC the details of which is which.
I dare somebody to do this. I totally dare you.
