Born in a barn?
Lacking in the social graces?
Possibly completely devoid of class?
Why else would you tap a woman's stomach and ask, "Have you gained weight?" And subsequently, after being stared down with a look of death tempered by disbelief, would you continue on with, "Is everything O.K.?"
What planet is such a person from? Apart from the social taboo of discussing a woman's weight, what about the invasion of personal space? Why should your victim feel obligated to start explaining PMS bloat or just having a "fat day" to the likes of someone like you?
My paternal grandmother used to say whatever came off the "top of her head," but I can't recall her being rude or making such a faux-pas. She was cute, even funny. This was neither.
