I agree, Partner Dancer. I didn't really intend to support the statement that a lot of people quit because of it, just that it's a problem. One of my students did tell me that a woman he worked with came once, had that kind of experience, and never came back because of it. My response is, "Why let one person ruin something you want to do? There are people like this everywhere, not just in dance. Shrug it off, complain about it to your friends, but keep dancing."
