You're talking to an Ex-Cubs Scout member... Until I moved away and the scouts wasn't open when we went this year... -.-
Anyway, Even in my 3 months of being there, I learnt quite a lot. I learnt how to start fire with rocks, some archery, how to set up shelter and how to clean water. Luckily, I live near quite a lot of greenery, including lakes, canals and even a forest, so I have all my resources. For food? Well, where I live is quiet so most people stay in the backgarden and leave their doors wide open. Simple as, I would sneak in like a nerdy ninja and grab all I can, and return to shelter. I would mostly get tinned food as they are delicous and easy to cook on some fire. I don't know how I would wash, get new clothes or anything like that, I suppose if I get bored I'll just turn feral... or naked. I would spend my days looking for food or going fishing (With handcrafted rod, of course) and building my own entertainment. And of course, climbing trees and cracking birdies eggs(Of course I wouldn't do this, I am a pacifist and I love animals
) to eat scrambled egg. Basically, if I was kicked out, I would block myself away from civillization and basically live like Animal Crossing, and tame a Fox and follow it around
Seriously, I am quite independent and I hate it when people butt in to my sandbox and ruin it
