Where's the heat?

I forgot to mention this earlier... but the heater in my house hasn't been working. It wasn't a problem until recently when the temperature outside started getting colder. Yesterday it got down to 59! It wasn't freezing, but it was pretty cold. My father-in-law came over and fixed it for me. YAY! He determined that I needed a new thermostat. The cool thing was, my brother-in-law Nathan happened to have an extra one and he only lives five minutes away from me. Even though our family has it's petty squables I still feel that we are good about coming together to help each other out when one of us is in need.
