Under any circumstances DO NOT teach your partner on the dance floor, especially if you don’t know your partner very well.. This is extremely rude, degrading to some and just bad manners. If someone wants you to help him/her – find a suitable place and dispense your enormous knowledge if you must. Do it anytime and anywhere BUT on the dance floor during the party. If you come across a beginner ADJUST to his/her dancing level and make him/her enjoy the party. Period.
