Sounds like gentleness is a common trait with this breed and the horse she rode was wonderfully sweet and gentle. How about the laziness? My daughter is used to a horse that likes to go and is very responsive to her so the lazy thing is a different kind of work for her! She really enjoyed the ride though and is looking forward to another.
Sj - that barn looks great! Do you ride with the trainer? How lucky you are to have such talented trainer in your area! Have you been to one of the Andreas Hausberge clinics? There was one last summer in our area but we couldn't make it. Would be fun to watch though! We might go audit a Guenter Siedel clinic in a couple of months for fun.
