Listen, if you really think you'd be better off out there in a world full of people you can't talk to, mutated animals, in the middle of winter, in terrain you don't know... no one is forcing you to stay. We can get you some rations and you can go. But I've been living off this land for over a year, and I've seen firsthand what's out there, and I wouldn't assume I could do it on my own. No one would be able to reach you or find you if they needed to, either. You'd be cut off from us, and if someone who knew you showed up, they'd never find you.
But it's up to you. If you think you know what's best, that's your choice.
