Hi Mary,
Loved your post because (a) I am a Latin/Ballroom dancer by serious hobby and more importantly (b) the dynamic of lead/follow in dance is one of the very best analogies for modern day leadership.  In addition to your questions, I add that the follower in dance is (and must be) very strong in their own body.

It is a myth that the leader actually moves the dancer around the floor. The leader only sets the direction and the follower must be ready and react with the slightest touch of direction.

I could go on and on yet I will spare you all my huge enthusiasm for dance.  Suffice it to say I have learned as much about leader/follower as I have about dance -- in my lessons.

I will RT your post on Twitter for sure!
Kate
