Read it through once

Of course I suffered some surprises, along at first, before I had become adjusted to the changed state of things. I met young ladies who did not seem to have changed at all; but they turned out to be the daughters of the young ladies I had in mind--sometimes their grand-daughters. When you are told that a stranger of fifty is a grandmother, there is nothing surprising about it; but if, on the contrary, she is a person whom you knew as a little girl, it seems impossible. You say to yourself, 'How can a little girl be a grandmother.' It takes some little time to accept and realize the fact that while you have been growing old, your friends have not been standing still, in that matter.
