I think you just described my Dad and his whole tribe. He has so many friends and they all trade favours, all the time, there's this deep connection and they read people by how much they give to others, in balance of course. He'd give the shirt off his back to just about anyone, but he knows when someone is only out for themselves. He loved cars so much he built a business around it, but it's essentially become a men's shed. I think you're spot on, and that's a great test, if someone is willing to bust a knuckle open, trying to shift a tight bolt, with you, you know they're a good one.
