My wife has been keeping her mom at arm's length for months because of the OM. She "wouldn't understand" that it's harmless. Now, my MIL has the advantage of being being able to be hung up on or avoided. I'll encourage her to talk to my wife.
I know my wife is starting to chafe at having someone around her all the time -- no chance for private sweet nothings with the OM.
