my air conditioner is on (set at 78F) 
So is my mom's furnace. That's above my melting point.
Anyone who visits my mom is in physical distress by the time they leave. I'm the only one who takes her to the store and it goes like this. I call her up to make sure she's ready to go before I leave my house. When I get there I have to find her hearing aids if she doesn't have them in. Her coat pockets are her favorite hiding place. Then I have to find the shopping lists she didn't remember making, look at the front and back of each one, and cross off everything she has listed 2 or 3 times. And I cross off all the things she already has in various locations in the house, and check to see if she has bread, milk, cereal, eggs, and dog food. Then I have to wait for her to take off her too-big grass-stained shoes that are held together with duct tape, because she's embarrassed to be seen in public wearing them. So she squeezes into a pair that's way too small, and I know she'll complain about her feet hurting all the way to the store and back. She's a hoarder who was raised during the great depression and won't buy one single pair of shoes that fit. Never mind the near quarter million dollars she has invested. Then she looks at her jeans and decides if she needs to change them or not. She can't see the dirt and grass stains I do so she's ready to go. Or is she?
I have to find her purse. Then her money. And I tell her no, ten dollars isn't enough, and I have to find the money she squirrels away in different parts of her wallet, card holder, change purses (plural), and around the house. Finally she's finally ready to go . . . to the bathroom. Then she grabs my coat and I tell her that one is mine, and she puts on one of hers, with or without duct tape. And that one isn't warm enough so she puts on a different coat. Then we have to look for a hat, or she waits until we're in my truck to tell me she needs one. While all this is going one we have to find her house keys, and when we do she has to check multiple times to see if she has the right key, because she doesn't believe me when I try it myself to be sure, and tell her it is. By that time I'm sweating bullets. It's so hot in her house I feel like I'm going to faint. I take her to the store to get the 4 things she actually needs and she buys whatever strikes her fancy in the meat department. Travel time to her house and back: 30 minutes. Time to the store and back: 8 minutes. Total time: about 3 hours. That much time in a sauna is way too long, especially if you've had a low grade fever and swollen lymph glands since the year before. When I had central air at my other place, I set it to 72 degrees, sat around in my shorts, and loved it. I can't wait for autumn to get here.
