What exactly are you supposed to do if/when you encounter a black bear?

Tinyfaery, her wife, my g/f and myself were up in North, Michigan, last weekend and my g/f got talking about black bears. She said to me that you’re supposed to fight them when you come across one.

We were joking about running from the bear (her and I), because I am way faster (the way that she runs = “twinkle toes”), so, she’d get eaten because she’s so slow. ;) And, I’ve heard that you’re not supposed to run from them.
