I've encountered quite a few new mechanic types who have a hard time with one or the other when explaining lefty loosey/righty tighty or clockwise/counter cw so I just use both. Often they can't grasp either until they have some actual experience. Also have to explain that it depends on what side of the fastener your looking at too. Spoke nipple direction seems to be the hardest to explain to people. Whatever explanation works is how I look at it.
