Tae Kwon Do, Karate, etc.? Ever had to use your skills?
No, but I'm acquainted with many of the Marital Arts.
Yes. I've studied Tae Kwon Do for many years. No, I've never had to use it.
I tried to learn Tae Kwon Do several years ago.
Unfortunately, the class instructor was the most humorless dyke in the world. The woman could suck the joy out of a roomful of puppies and kittens.
I committed a major faux pas at the class Christmas Party when I brought dip containing gelatin, which is a completely taboo among the vegan crowd, which of course the instructor was.
Needless to say, I never went back after the first semester.
