People tend to develop quirks as they get older. They get set into a certain habit of doing things, & it takes an act of God to dissuade them from it. I believe when you’ve lived long enough, you’re justified in having things your way for the remainder of your life. You’ve put up with all the crap that life has thrown at you & now it’s time to relax & care about yourself, I get it. However, whenever I visited my Grandparents home lately, I found that they set an unbearably low temperature on the control unit. I do not remember them preferring it ice cold in my younger years, however now they insist on it. I try to avoid confrontations over the control unit with them whenever I visit. It is their home after all. However, when it’s just as cold in the winter, that’s where I draw the line. Our winters are not necessarily mild around here, so I downright fear for their safety whenever they insist on setting such low temperatures when it’s already below freezing outside. What are they thinking? Their oil furnace is admittedly pretty old & has seen better afternoons, so I decided to do something for them. I bought some portable space oil furnaces for them to set up in their many rooms. This way they could at least have some effective source of heat while I was in the worst of the winter. The last time I visited their home, space oil furnaces were still set up everywhere, so I believe they are using them. I hope they are not just taking them out for my benefit before I arrive!
