Last June, my housemates and I decided to host an outdoor party. All of us went to a good deal of effort plus expense. During the week prior to the get-together, we spent long hours making sure the patio and gardens looked their best. All of us thoroughly cleaned the house, rented a giant tent, put out tables and chairs, and bought plenty of food beverages. On the day of the get-together, the outside temperature climbed into the high eighties and the air was sticky. Although we encouraged our guests to remain outside on the back patio or on the lawn, people kept walking inside to cool off in the air conditioned house. Hoping to conserve a bit of energy, I made sure to raise the temperature control setting a bit. I knew the door to the outside would continually be opened and closed by people using the bathroom. I didn’t want our air conditioned air escaping outside, and I hoped to lessen the workload of the cooling system. However, when I went inside I heard the A/C blasting at maximum capacity. Someone had turned the thermostat way down and left the patio door wide open. After that, I stayed close to the thermostat. I knew the upcoming utility bill was going to be super costly, plus I was a bit upset about a potential A/C system malfunction. I was tempted to push everyone out of the house and lock the door. My mates and I ended up with a real mess, both inside and outside of the house. That’s the last time we’ll will host another summer outdoor event.
