I don't know, this guy sounds like a treasure to me.

He doubtless knows how you're responding to his comments/advice/instruction and simply wants you to consider another point of view. Some of the most unorthadox players have been the ones to radically change the perception of music, from Beethoven to Hendrix. The price is right, though it's almost embarrassing to pay someone so little, and you could get more lessons elsewhere too, as you're able to put together the money. Someone suggested recording his stories and it's a great idea. Record his style too, it might come in handy in the future.

Some gems are polished, some are in the rough. Either way they're worthy. Just don't expect him to be something he's not, or do something he dislikes, but exploit his resource as he allows, and find other stuff elsewhere. If he really depended on teaching income he'd charge more and provide conventional practices. My guess is he likes having you around.

Good luck. I'd like to know what you decide to do.

Peace, Mooh.
