As a kid， I spent my summers with my grandparents on their ranch in Texas. I helped fix windmills， vaccinate cattle， and do other chores. We also watched soap operas every afternoon， especially "Days of our Lives." My grandparents belonged to a Caravan Club， a group of Airstream trailer owners who travel together around the U.S. and Canada. And every few summers， we'd join the caravan. We'd hitch up the Airstream trailer to my grandfather's car， and off we'd go， in a line with 300 other Airstream adventurers. I loved and worshipped my grandparents and I really looked forward to these trips. On one particular trip， I was about 10 years old. I was rolling around in the big bench seat in the back of the car. My grandfather was driving. And my grandmother had the passenger seat. She smoked throughout these trips， and I hated the smell.
在我还是一个孩子的时候，我的夏天总是在德州祖父母的农场中度过。我帮忙修理风车，为牛接种疫苗，也做其它家务。每天下午，我们都会看肥皂剧，尤其是《我们的岁月》。我的祖父母参加了一个房车俱乐部，那是一群驾驶Airstream拖挂型房车的人们，他们结伴遍游美国和加拿大。每隔几个夏天，我也会加入他们。我们把房车挂在祖父的小汽车后面，然后加入300余名Airstream探险者们组成的浩荡队伍。我爱我的祖父母，我崇敬他们，也真心期盼这些旅程。那是一次我大概十岁时的旅行，我照例坐在后座的长椅上，祖父开着车，祖母坐在他旁边，吸着烟。我讨厌烟味。
