If you must leave in an emergency, try to fill your spot with a substitute. By all means, tell the others why you must leave. It might be said that square dancing is an activity where everyone is responsible for everyone else's happiness. A square is not made up of eight individuals working independently, but rather in one unit with no individual person attempting to show off or be a star . The real pleasure comes when each person does his share making the square run smoothly.
Square dancing can be strenuous exercise.
If you are too tired to dance, sit out. Sometimes you can learn a great deal just by watching and listening. If another dancer is watching and listening, don't insist upon talking. Square dancing is a social event but not a place to socialize during tips or rounds even if you are not dancing. Take the opportunity to get acquainted with others in the square.
