It depends on the dwarf. Really, they are individuals, I've only met 2 dwarves, one when I was younger, there was a dwarf living nearby, and he had a little scooter, tiny little leather jacket, long hair. He was a pretty cool dwarf, didn't let it stop him from doing what he wanted. That was back in the 80's, when there were a lot more dwarves about.
The only other dwarf I met was a friend of my grandmothers, and she was a right miserable little cow.
Time Bandits was on TV at the weekend, damn that's a good movie if you want to get your dwarf-on.
