From an ex-student from about 6 years ago via facebook. She's applied to study teaching because I inspired her in Year Six. I've had a smile on my face ever since. If I wasn't a facebook-er, I doubt I would ever have heard from her. Hooray for new technologies!
Makes me feel like the last 9 years of teaching might have been worth something.
That is very special. You should be very proud of the positive influence you had in this woman's life!
I've sent that kind of letter to a number of teachers and mentors in my life. I think it's very important to express gratitude to the people who help shape you and influence your life.
That is wonderful. I know it's much better confirmation coming from a student that you are a great teacher.
