My grandmother just told her niece on the phone that we like to keep things "real cold" in our house. The thermostat reads 77°F.

Now, the humidity is low and the windows are all open, so it isn't hot by any stretch of the imagination. No, we don't have fans on, and no, we don't need them on right now. If it gets to like 82, we'll need them on. And also, I totally get that she may feel cold. But at the same time, I can't stand the way she frames the world. We keep the house cold and we talk super quietly. Why can't she be like most older people and just admit that she is the one who feels differently because of the thickness of her blood, the speed of her metabolism, her smaller intake of food, and her low activity level, and that she had hearing loss? I feel bad for her for having to deal with all of these things which reduce her ability to perceive reality to its fullest, and that she can't just pop out at will and experience life as she did when she was younger. I just wish she didn't say things to my mom like, "You're always warm. I wonder why that is." The truth is, my mom is pretty heat-tolerant, and so am I. When I go out in public, I have to accept that most people in the U.S. feel hot before I do because they are dependent on air conditioning. But I don't act like my temperature preferences are average for the U.S. because I know they aren't.
Alright, end of rant. Despite my nuance, I expect to see many comments from people who didn't read the rant and believe I do not understand that she perceives the air temperature differently because of her age.
