Jack, you are too modest. We all have things to teach each other and we can all learn from each other. You make those interactions particularly easy and enjoyable. There are more important components of learning than just dispensing facts - like setting the example that it is joyful to practice the act of giving "time, effort and patience", and doing so with style, grace and eloquence.

Cheers, my friend.
