Leading lessons with miniature horses

Today's lesson. This is my second visit. Last visit all of these horses were not leading well. I only worked with this particular horse a few minutes last session. I am demonstrating proper leading. The goal is, I don't feel him, and he does not feel me. Our goal is lightness.
Even though these horses are small,they are still horses, they believe they are 17 hand's tall. In their hearts and minds they are as big as any Budweiser Clydesdale. You do your horse, foal, or mini no favors by allowing them to get pushy, step into you, or drag you, it's also not fair for you to be constantly pulling on them. Leading a horse, is similar to Heeling a well behaved dog on a leash. The horse should walk when you walk, stop when you stop. and if you turn to the right, he should move his feet and body out of your way.
