Another way to think of Twosome is to imagine that the other dancer
in your Twosome unit is like your counterpart in another square. If
you start out as the #2 Lady, your counterpart in the adjacent
square is also the #2 Lady. As you execute each call, imagine
the other square moving closer and closer to your square, with your
counterpart eventually moving adjacent to you. Even though you are
both doing the exact same calls and movements, you can never switch
places into the other square, so your counterpart will always be on
the same side of you.
