It's probably due to attention deficit disorder* and the fact that if he didn't say something right then and there, he would have forgotton it. For me, that spontaneity made those early guitar lessons fun. Of course, my mind works like that too. It could very well drive some people batshit.


* Named such across the board, with no thought about degree or whether or not it works for a person. If you're surrounded by folks who can either ignore you going from point A to point Y.5 for no obvious reason OR actually understand what what prompted it, it's not a 'disorder'. If you pay full attention to what you're doing, it's not 'attention deficit' just because you happen to shift focus a lot. Rapid Attention Shift Syndrome maybe.
