On a crowded dance floor, it is common to bump into the couple dancing next to you. If you’re part of a collision, stop dancing, make sure no one is hurt and apologize. If you are a leader, you ultimately are responsible for where you place your partner, but, as a couple, you should both be aware of your surroundings. If you are a follower, you should act as the leader’s back-up set of eyes. If you see a collision about to happen, tighten up your frame and give the leader’s arm a squeeze to let him know you’re in a tight spot.
