 Well, I get the gratification of doing good to others. I find that I really enjoy this program a lot. I find that it's really a very broadening experience for me. I've worked with students from people, tutors, 2Ds, from Nepal, Korea, and now Turkey, most recently. I find it very broadening. When you work closely with people from other countries, it's very interesting to find that we're all basically the same, no matter what culture we come from, that we have the same problems, the same successes, and so forth and so on. Additionally, most retired people like me look for ways to keep their mind active, and this helps. It certainly helps me to review my understanding of the rules, or lack of rules of communicating in English. I'm constantly brushing up on my own knowledge of why we do certain things in English. I always did them that way, but what's the rule? Or is it a rule? It's something you have to learn and not seek a good theoretical explanation of it. I've found it to be very rewarding for me to work in this program.
