False. I have plenty of warm clothes, and didn't have to "stock up." And my building is very well insulated, so I rarely have to turn the heat on at all. The thermostat is set to about 71 in the winter, I move it down to 68 at night, and it just stays that way. I rarely hear the furnace go on. But I do have a little space heater and an electric fireplace for extremely cold days.
You are going out to enjoy the beautiful autumn weather, every day.
