You have my first two-handed upvote.

Gonna need the story on that one. It reminds me of trying to teach my grandpa to use a mouse. Not his fault, he had a fifth grade education then went into the mines. This was all magic to him. So every time he wanted the cursor to go higher on the screen he'd lift the mouse in the air. We couldn't get past it- this motion on the horizontal plane becomes that motion on the vertical plane.

I'm sure I could teach a man like him now that I know how to teach. At the time I was an impatient young teen.
