" Adults love to tell teenagers that “one day” and “sooner or later” plenty of things are going to happen. They love to say that things happen “before you know it,” and they really love to impart how fast time “flies by.”
I would learn later that almost everything my parents told me in this regard turned out to be true. College really did “fly by.” I did change my mind about Keanu Reeves “sooner or later.” I was on the other side of thirty “before I knew it.” And, just as my father said that afternoon, “one day” I was going to need my sister very, very much.
