As a kid, I spent my summers with my grandparents in Texas. And every few summers, we’d __16__ the caravan (旅游团队), a group of Airstream trailer owners who __17__ together around the U.S. and Canada．
I loved and worshipped my grandparents and I really looked __18__ to these travels. On one particular __ 19__ ，I was about 10 years old. I was rolling around in the backseat. My grandfather was __20__ . And my grandmother had the passenger seat. She smoked throughout these trips, and I hated the __21__.

When I was satisfied that I’d come up with a reasonable number, I poked my head  into the __25__ of the car, tapped my grandmother __26__ the shoulder, and proudly proclaimed, “At two minutes per puff, you've taken nine years off your __27__!” Because the ad said, every puff of a cigarette takes some  number of minutes __28__ smoker’s life．

My grandfather was a highly intelligent, __32__ man. He had never said a harsh word to me. He pulled __33__ onto the shoulder of the highway. He stopped and got out of the car, __34__ me, and after a bit of silence，he gently and __35__ said, “Jeff, one day you’ll understand that it’s harder to be kind than clever.”
