If I had to pick a stranger to watch my back, I'd take a metal head any day. There's always a few assholes in ANY group, but for the most part, they are consistently the nicest people I've ever met.
They can kick some ass with the best of them, but will help you up when you've had too much.
i'm a firm proponent of making animal therapy a standard thing available to everyone, imagine how much better everyone would feel if you could go cuddle kitties anytime you feel a bit down!
I'm blessed enough to live in an area where there are a bunch of cuddly cats walking around the streets and any time i'm not travelling on foot or bike i'm a bit sad because it means i won't meet a cat :(
