Jeremy- I'm glad you do know what my point is. When I reply to posts here I often am writing for others who look for their answers but might not be the OP themselves. I will say that your faith in peoples' ability to follow/understand directions and execute them with their hands is a noble one but often enough not seen in actual life.

I teach various bike mechanical clinics and often watch the students' hands do the opposite of what I direct them to do. This is why I feel the need to be specific to the rotational direction and not just which way to push on a wrench handle. I also use the various rotational direction sayings like "right's right and left's wrong" when talking with people BUT I make sure that they understand I'm not talking about wrench handle pushing. After 40 years of describing to my customers and students I still need to remember that many people never needed to do more then screw in a light bulb before in their life. IMO more and more people have had less and less hands on experiences WRT things mechanical, as the years go by. I've had a few people who I discuss this stuff with suggest that the advent of the digital clock (and radio for that matter) and the interweb produces people with less and less understanding of things like rotational directions.

Thanks for not taking my previously direct comments too personally. Andy.
