It's always important to actually go into the home to check on the elderly. It happens so often.
You're not nuts. But I don't really want to relive the days of my youth without such a thing as AC in the same conditions we have today, summer after summer.
I watch the weather reports. When it has been warm and it's going to be cold, I like to close the house up to retain some of the warmth and vice versa. My wife is the complete opposite. She'll keep the windows open till the weather turns and immediately turn on the AC or heat.
