You never know what people have been through or how they’re going to react to things because of their past. This is especially true when it comes to people who have lived through traumatic events which have left a lasting impression on their psyche. You can’t tell who has been through abuse, violence, or poverty before in their lives just by looking at them. This makes it hard to be sensitive to differing needs all the time. This was especially true, I realized, when it came to my aunt and her central heating and cooling system. I never realized that she had previously been in an seriously controlling relationship, which included controlling the indoor air temperature to an severe degree. Apparently, my aunt’s former husband was a bit of a curmudgeon when it came to energy bills and energy expenditure. Because he works out of the apartment all day long, he did not know that my aunt should require any central heating or cooling. He did not want to pay the energy bills for her to be comfortable all day, so he had installed locks on the temperature control to prevent her from altering the central Heating and A/C system settings. This meant, she lives at apartment in fluctuating indoor air temperatures and suffered for nearly 10 years with unbearable air quality; Of course, I had no clue that she was so sensitive about her central heating and cooling system settings. The last time that I was going to see with her, I politely asked if my friend and I could turn down the cooling system a few degrees to which my aunt nearly imploded. Now that I know she previously lived under an Heating and A/C tyranny, I feel bad for trying to mess with her indoor air temperature at all. I tried to make it up for her by buying a smart temperature control and having a professional Heating and A/C professional upgrade her entire central Heating and A/C system. No one should ever live under those uncomfortable circumstances.
