I was talking with some colleagues of mine, today, during a coffee break at our premises, when one of them started complaining that he hadn't slept much the night before. One of his sons had been out with his friends for a cinema & pizza or something else he didn't want (or couldn't) know. He stood up, watching TV on the sofa in his living room, until his son was back home.
Some of us laughed at him; others sympathized, having had more or less the same experience; I tried instead to suggest him to be less catastrophic and more fatalist. At my words he turned to me and ironically smiling said: "Your kids are still young. Wait and see ... There will be a time when you'll drive them to party. There will be another when they'll take the car to drive you around ...".
