Maybe it's my general distrust created from my years in LA, but I was floored when my neighbor tossed me his keys yesterday.
I needed to go pick up a new washer/dryer, asked him for a tow hitch. He thought it was odd that I would want to rent a trailer, "when I could just as easily borrow his truck"!
I questioned him of course, he said it was cool as long as I didn't "wreck it on purpose", and he was serious!
So I took his Tacoma, picked up my shit 'n brought it home... dropped off his truck, gave him the keys back, he says "naw it's cool just toss em back in the truck, I'll get them tomorrow".
THE most trusting person I've ever met.
