Square dancing is all done by older people, they usually don't have a job anymore, and this is the time they need to find something to do, square dancing just solves this problem for them, by square dancing, they can exercise, they don't have to stay at home every day, and they can dance with some like-minded people, and communicate with each other, and in this way they are happy.
I often encourage my mom to go to the square dance together, because usually she is just at home, and does not go out, and there is no one to accompany, feel so lonely, I hope she can be happier, can go out and some of the small friends with the square dance, but also can exercise, why not.
