Robert Frost wrote in "Mending Wall" that "good fences make good neighbors." In dancing, good fences leads to LOUSY dancing, especially Argentine Tango. Many dancers don't realize that the fence they put up ruins their dancing and makes it impossible for their partner to dance well. The fence is the woman's right arm and the man's left arm. Tango is meant to be danced closely and the fence keeps the partners apart. There is an alignment in tango. The partners should be in front of each other, connected at the sternum. The woman's fence, her right arm, pushes herself into the man's armpit, which is the worst body location. When the woman wedges herself into the armpit, her left shoulder is locked. A locked shoulder can't rotate and limits the woman's ability to pivot and execute ochos. I'm short so when the woman pushes on my left arm, it feels like my shoulder will be dislocated. I have no choice but to force her arm downward against her body or let go of her hand and hold her bicep to relieve the pressure on my shoulder. Her muscles become so tight that they grip. The shoulders go up and the woman takes tiny steps because she can't move well. The man's fence, the left arm, is so tight he pushes the woman through ochos. Some men confuse pushing with leading. They are NOT the same. Pushing will throw the woman off her balance. Then the man will tell the woman what she's doing wrong. Why women tolerate being lectured by men who lead poorly is a mystery. If you want to dance well, take DOWN your fence and stop dancing with partners who won't take DOWN their fence.
