It has been very cold the past couple of days. Yesterday morning the temperature was in the minuses (-2 according to the thermometer in the car), and we haven't had any heating except for a couple of cheap electric heaters. Even the heaters haven't been very effective - the chimney was open to the skies, so any hot air we did manage to generate disappeared instantly. This meant that Thursday night and Friday morning were pretty miserable.
