If it's so frustrating to define, explain and clarify for some people, I guess that's why some people are great teachers and some people make good Janitors.
Some people want a teacher to do their homework for them and expect the rest of the class to accommodate the situation.
Maybe truer words have never been stated, and both/multiple stations,(janitor, teacher,farrier/whatever, ) if done to the best of that persons ability, to me, are honorable,valued and necessary, but it does not mean that if a good farrier can or cannot teach, that it make him or her less/more of a farrier. ray
