You want to practice this exercise enough, that you can almost move
without thought. You want automatic responses. It’s important that you
perfect how you move now, because the next step is moving with someone
in tow.
And so, on to Stage Two....
Now, you are going to go back into the crowds, but this time, you are
going to take someone with you. I prefer to take someone who isn’t trained
to move efficiently. A child works (your own preferably or a friend’s, with
permission of course). Or enlist the help of a clumsy friend. Or have a
friend act the part.
