Thank you very much indeed for your most interesting and informative letter of October 11, 1969.
………
I appreciate very much your taking the trouble to write us such a long letter. It must have taken you two or three hours of your valuable time. Perhaps you should arrange among yourselves to take turn to do this.
Letter from Professor Y.C. WongOctober 17, 1969.
You said you are a beginning teacher, but what you said in that letter as well as an earlier one about what a teacher should do is very similar to what I learn from my long experience as a teacher. If you keep on using your imagination and experimenting in this way, you may some day become an outstanding teacher of mathematics.
