Re: What do we owe?
I have had five martial arts instructors. Of the five instructors three did not charge for teaching, one charged a minimum fee ($5 per hour) and one was a McDojang that charged money at every opportunity.
The McDojan instructor I owe nothing to, he got paid more than what he gave.
Three of the other four I owe thanks and respect for their knowledge, ability and what they taught me.They gave more than what they received.
The last one is second to my father in giving me the foundation for my life. He gave infinity more than what he received. What do I owe him? To be the better person he would expect me to be.
