Granite, maybe she has Alzheimers? My former chiropractor had it, and i had no idea. He still did excellent work, but i did think he had been a little goofy a few times. He had a younger guy working with him, and that guys wife as receptionist, so i guess they were handling him. Sometimes my appointment would be switched to the younger guy without them really saying why. And i wasnt going very regularly, so this was over several years, until he finally did retire.
