"I didn't know that."
"Steve if we stack up everything you don't know we have the Himalayan Mountains" Jesse
This has stayed with me the last decade and a half, along with, "it is not your world you just live in it" and "you are not a missionary", those comments have shaped my world view. People are their own. It is not up to us to correct their misconceptions it is their right to be wrong and everyone trains for their own unique and very private reasons.
When you teach someone give them something that they can use and use right now. Each class give them something that is valuable and useful then and on the way home.
I miss Jesse's practical advice.
