It’s a silly thing, but when I’m bidding farewell to the children, I often say, “Hasta la pizza!” This bugs my husband who, if he hears it, hollers, “That’s not a saying!” The kids, on the other hand, like to go one better and reply with “Pasta la pizza!” Ironically, this bugs me, because it’s not how I think the saying should go. 😛
P.S. Sometimes we also say, “Taco to you later!”
