The instructors deserve your utmost attention.

This is not a social time, other people and the instructor are trying to concentrate.

While in the class, it is assumed you will attempt to do whatever the instructor asks of the group (you) when dance related.

If you are not getting it, the instructor has a responsibility to the entire class.

Asking excessive questions is selfish and hogs a lot of time away from the group.

Wait till after class or better yet, schedule a private lesson.
