" Fifty years isn’t too bad. With luck you might see it happen when you’re a sweet, old granny, dandling big fat babies on your knee. Actually”—he held up a hand, interrupting Kitty’s cry of protest—“no, that’s wrong. My projection is incorrect.”
“Good.”
“You’ll never be a sweet old granny. Let’s say, ‘sad, lonely old biddy’ instead. "

― Jonathan Stroud , Ptolemy's Gate (Bartimaeus, #3)
