Different values. Personally, I think it's best to have a professional teacher of yoga and dance, look in the mirror and standardize the movements. One is to spend money, and the other is that only teachers and students can see it. Some people don't want to spend that money or work hard. They just learn a little fur and like to be seen. That's a square dancer. As for the one who only revolves around grandchildren, she doesn't even have this interest. The meaning of her life is entirely based on others.
Besides, I really don't think square dance is fitness. If you have done a fitness activity seriously, you will know that most square dances are really inefficient and unattractive. Doing housework and taking care of children can't be called exercise at all, it's called labor.
