Cold, cold winter

The temperature is dropping quickly here, but so far, not one of my schools has decided to bring out the heaters. Even worse, in most of the classes, they keep the windows open. I just can't figure it out! My toes went numb today and I couldn't stop shivering, but some of the students were still wearing shorts! Is there something I don't know?? I know I've lived in pretty warm climates for the last 9 months or so, but I am not that weak. I finally asked one of my teachers today about it, and he agreed that it was very cold. He said that they would be working on getting heaters in there. If they don't, I'm not sure I will survive the winter.
