A teacher in winter is happiest because they get to teach! The kids can't go out and play because it's too cold. They all have to come in and stay warm as the teacher teaches!

Teachers can teach the most about Japan in winter by going to きょうと. きょうと is where all the old temples and history of Japan is centered. And it's really gorgeous when it snows.
