One of my favorite memories of my mother, who died in late 2008, is her voice pronouncing (sometimes ironically, sometimes not) one of her"mom-isms." My mom's mom-isms were often malopropisms, though most of the time my mother meant them to be, unlike the character from Sheridan's play, Mrs. Maloprop, who mangled maxims.
My mom's most famous is, "We'll jump off that bridge when we get there." That is the only form of that particular mom-ism I use, to the point where my younger daughter asked me some years ago, "Mom, why are we going to jump off a bridge?"
Well, I answered, that's kind of an interesting story. You see, we're not going to actually jump off a bridge, the expression is, "We'll cross that bridge when we to it." But my mom always said it as "We'll jump off that bridge when we get there," as a kind of joke to help us not worry about a particular situation.
What is your favorite Mom-ism?
