The heat is on. July and August, for many of us, puts the temperatures up in an uncomfortable range. These stifling temps remind me of my mother-in-law. She had a wall air conditioner in her condominium, but she would not use it. Even though the noon hour was my usual time to see her, during hot weather I'd run over in the mid-morning and mid-afternoon, as well. I'd turn on her AC, as she'd sit with her windows closed, draperies closed and virtually no air.
