If you ask a group of teachers about the types of gifts they like the best, notes from students and written sentiments from parents consistently top the list. You'd think after a few decades of teaching, teachers would become less connected to their students and start to think of the process as a job instead of a calling, but happily, that's not the way it works. Teachers have a big influence on the way your child views the world around him, and most of these dedicated professionals take their jobs very seriously. If you feel grateful for a teacher's vision, sensitivity and commitment, write him a note to explain why. It's one of the best gifts you can give a teacher, and one that's likely to be remembered long after the bell rings.
