Tommullan, isn't it fascinating how we can "hear" something but it doesn't click? I find the learning process fascinating. We're lucky that we have have two instructors, male and female for our group class and sometimes one will say something just a little different than the other and the light bulb will go off. I truly admire the patience and creativity of instructors. At least the ones I've had so far; I'm aware not all have that same temperament.
