One day back in the mid-1980's, about 8 years after my Mom had died, I got a phone call from "Mrs."  My Mom was "Mrs", I am "Miss" or "Ms."  So the first thing that popped out of my mouth was "Oh, I'm sorry! She's dead!"  The person on the other end was so flustered, that after stammering an apology abruptly hung up!  LOL

Now when I get a call for the "Lady" of the house, I just tell them that they are dead.  That ends the call pretty quickly.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
