I had the air conditioning on yesterday, because it was warm and humid. I woke up this morning, and I was so cold I was shivering. I quickly dressed, turned off the air conditioning, and donned a sweater. I was going to turn on the furnace, but I still hadn’t had it serviced. I pulled my sweater close and went to the closet. Somewhere, in the back of the closet, I had a small space heater, and I was planning on putting it in my office. I knew I was on an impossibly tight schedule, and I was doubting I was going to make it on time. If I was sitting in my office shivering, I knew I wouldn’t get my work done on time, and I would end up being penalized. I called the HVAC company to get my furnace serviced, and then I found the space heater. After plugging it in under my desk, I could soon feel heat flowing over my feet. Once my feet got warm, I felt less shivery. The space heater was doing its job. I was just getting into the groove and my work was going well when the HVAC company called. The HVAC technician was going to be at the house within an hour. I didn’t expect him so soon, and I wanted to finish one part of my work before he showed up. Once the HVAC technician got to the house, it took so long for him to finish that I gave up on my deadline and called the boss. I told him I was going to be a day late because of heating problems.
