M.M.
I had a boyfriend years ago that refered to his ex as THE EX. I said, "She has a name and it's Sicklefritz." So every time he said THE EX I corrected him, he finally started saying Snicklefritz, or whatever her name was, I can't remember, but I too can't stand when people do that and I do correct them.
Nor do I allow people to say "the hubby" or "the wife". I will stop converstaions and ask what the respective person's name is and then go ahead and correct them.
Now on here I find myself typing my hubby's or kiddos' names then retyping something more ambiguous. My name and city is enough info on the web.
It really irritates me.
