I'm sorry you've been feeling so scared. Yes I would certainly agree that whispering in the kitchen is rude. Perhaps your son & his wife are experiencing some marital discord? Anyway... it's been a couple of days since you posted this. Hopefully you're feeling at least a bit better. I know that, as I've gotten older, fears of various kinds as well as paranoia, have become things I tend to experience as well. They're not pleasant.
