Yeah, every now and then when I'm teaching, I hear myself explaining something the students don't need an explanation of. Then I realize I'm correcting an earlier version of me, for something he wrote in his notes.Ain't it something? I read some of the old notes I find in the odd box of stuff and I think "What the hell was I talking about?"
Thinking about it.....probably the same short hand nonsense that any kid training thinks.
