As Helen pointed out to me,
when you are a man the corner positions don't change, and the concept of 3rd & 4th
corners helps (because 1st corner is always "diagonally down from 1st place", you
have a fixed reference point) - however ladies who have to dance on both sides don't
have this fixed point, so they have to make even more of an adjustment to work out
where 4th corners are.
