I always knew we were a fairly odd family. First there was me. Too tall. Too skinny. Too orange. My mum was lovely, but not like other mums. There was something solid about her. Something rectangular, busy and unsentimental. Her fashion icon was the Queen.Dad, well, he was more normal. He always seemed to have time on his hands. After giving up teaching university students on his 50th birthday, he was eternally available for a leisurely chat or to let me win at table tennis. And then there was Mum's brother, Uncle Desmond. Always impeccably dressed. He spent the days just, well, being Uncle Desmond. He was the most charming and least clever man you could ever meet. His mind was on other things, though we never found out what. And then, finally there was Catherine. Katie. Kit Kat. My sister. In a household of sensible jackets and haircuts there was this, well, what can I call her, nature thing. With her elfin eyes, her purple T-shirts and her eternally bare feet, she was then, and still is to me, about the most wonderful thing in the world. All in all, it was a pretty good childhood. Full of repeated rhythms and patterns. By the time I was 21, we were still having tea on the beach every single day. Skimming stones and eating sandwiches, summer and winter, no matter what the weather. And every Friday evening, a film, no matter what the weather. And then once a year, the dreaded New Year's Eve party.
我向来感觉我们家很古怪， 第一个就是我。太高，太瘦，太黄。我妈是个美女，但跟其他妈妈们不同。在她身上固有的几点：不落俗 套、忙碌以及从不感情用事。她的时尚教主是女王。我老爸呢…他更普通，他总是看起来很悠闲。50岁生日那天从大学离教之后，他就常常跟人闲聊，或是跟我打乒乓球，让我狂赢他。然后便是我老妈的哥哥，德斯蒙德舅舅。他的穿着总是无可挑剔，他每天就是做他的德斯蒙德舅舅，他会是你见过的最帅最无脑的家伙，他的心思都在别的事情上，虽然我们从不知道是什么。最后一位就是凯瑟琳，凯蒂，我的妹妹，身穿居家服，发型总是这个样子。我可以称她为天然尤物，她的眼睛、紫色T恤，再加上 她永远都是光着脚，在我看来，她还是这世上最美好的东东。总而言之，童年还是很美好的， 循规蹈矩，日复一日。我21岁以前，我们每天都还在海滩上饮茶，打水漂，吃三明治。不管秋冬，不管风雨，每周五晚上，都看部电影，不管刮风下雨，还有就是每年举办一次令人生畏的新年派对。
