My husband does just the opposite of whispering. He doesn't get louder than normal, but he does make all kinds of noises or says things that don't make sense. And this is very annoying because I can't hear the tv without turning it up, etc. When I ask him to whisper he says "ok" but then he doesn't. Not that I wish any of these awful symptoms on any of our loved ones, but I wish he WOULD whisper at times.... especially when he talks to himself when trying to go to sleep.
Hugs and Strength to all
