I really love going on vacation. I travel all over the world, just to do it. I have photographs of every landmark you might think of and I still try to travel. I bring my family to a distant destination almost every summer. We have been to several hot places and some really cold places. One very chilly winter we visited a colder region. We booked a room from a local motel and went to sleep for the night. When the room began to feel cold, I switched the HVAC system on. I didn’t think I needed to verify it was working properly and I walked over to the big bed and laid down. We fell asleep immediately, but woke up about 4 hours later, way colder than I have ever felt during my life. I could still hear the HVAC unit on, and that’s how I learned the unit must be broken. I curled myself up within the bed’s comforter and called the desk. The phone rang a bunch, but there was not an answer on the other line. I couldn’t imagine my luck. A business should always try to be certain they have a working HVAC system. This heater was, obviously, not working that well. My family and I laid around that freezing motel room for a long time. We were all bundled in place, dreaming of a working HVAC system in a much better hotel room. Finally, a number of hours after dawn, someone answered the phone near the front desk. I was angrier than I ever was on that cold night without any HVAC system to keep my babies warm.
