A little pespective: I am a teacher and I am in the process of moving. I have so many little gifts, candles, etc. that are special but require lots of boxes. :) My most cherished possession is the big, think purple folder in which I keep every letter written to me by a student or parent. On those cold, dreary winter days, I get a hot cup of coffee and read each one of those letters and reflect on the writer.
You sound like a very good teacher. :) As I mentioned in my other post, I wrote a letter to the editor of our weekly paper to thank my daughter's teacher for what she did. Teachers who care, as you do, make such a huge difference in a child's life.
