I am one of them. I have been in your house. My greatest compliment to you is that I hope I uphold your standards. Big hugs from a lifelong fan. You are a grace in all our lives, someone I thank God for knowing.
Teaching is a draining, sometimes frustrating task.
The high points always make up for the difficulties, but it is a test of patience. To remain happy and optimistic is really something special. You are teaching many of us simply by the example you set. After 50 years, you have so much knowledge and insight to share with us all. Your enthusiasm and energy after so many years is amazing.
