I got one neighbor who happens to be a long time friend. He is constantly borrowing my chidt with the exception of some things where I just say no way in hell. I tell him go buy his own stuff and he'll have it at the time he needs it. It doesn't sink in.
Then one day I was walking into his garage and overheard him telling his brother "don't go buy that kind of stuff, Jim has it all over there." I said "Bullschidt! Go buy your own stuff!" Scared the hell out of them. haha
