Door Was Left Open

My parents are super unique about their HVAC settings.

When I was still living under their roof, they had really strict guidelines about who could and couldn’t touch the temperature control settings, but basically, our parents and grandparents were the only people who had access to the HVAC settings.

I tried decreasing the temperature one evening when our parents went to bed and I thought I would get away with it, however our parents discovered the change as soon as they woke up and the house was frosty and cold. They grilled my brother and I to find out who changed the temperature and I eventually caved and told them that it was me. I was grounded for many weeks, which kept me, and my brother, from ever touching the control component settings again. Now that I’m a grown adult, I still don’t touch their control component settings. However, last weekend while I was going to see our parents, I accidentally left the back door of the house open for hours and nobody noticed. When I finally realized the mistake, I panicked just thinking about all the heat that had escaped through the door. For weeks I was sad about the heat loss and how much energy our parent’s furnace really burned. I was convinced that if our parents noticed a higher utility bill they’d discover what I had done and reprimand me, and possibly my brother, for it. I felt so stupid becuase I was fearful over accidently leaving the door open and our parent’s heating bill being higher. Of course they never said anything to myself or my brother because they would have no way of knowing.
