When I was in third grade, one of my classmates brought a sheet of racing car stickers to school to show off. The stickers were dazzling. I wanted them so badly that I stayed back during gym class and transferred the sheet out of the classmate's backpack into mine. When the students returned, my heart was racing. Panicking that I would be found out, I thought up a preemptive lie. I told the teacher that two teenagers had shown up on a motorbike, entered the classroom, rifled through backpacks, and left with the stickers. As you might expect, this fib collapsed at the gentlest probing, and I reluctantly returned what I had pilfered.

我三年级时，一个同学带来了一张赛车贴纸到学校里来炫耀。那些贴纸令人炫目，我实在太想要它们以至于趁着体育课留在教室，把贴纸从同学书包中偷出来，藏到了我的包里。当同学们回来时，我的心怦怦乱跳。因为担心我的行为会被揭发出来，我抢在大家发现前想了一个谎言。我告诉老师，两个在摩托车上的少年冲进了教室，洗劫了书包留下了这些贴纸。正如大家所想的，这个小谎言在温和的查探中被戳穿，而我也不情愿地归还了偷的东西。

My naive lying -- I got better, trust me -- was matched by my gullibility in sixth grade, when a friend told me that his family owned a flying capsule that could transport us anywhere in the world. Preparing to travel on this craft, I asked my parents if they could pack me a few meals for the journey. Even when my older brother snickered, I refused to disbelieve my friend's claim, and it was left to my friend's father to finally convince me that I'd been duped.

我天真的谎言符合我六年级时受骗的心态。相信我，我现在变得好多了。一个朋友告诉我说他家有一个飞行舱可以载我们去世界各地。为了准备这次飞船之旅，我问父母是否能为我准备一些食物，甚至当我的哥哥在一旁窃笑时，我还不愿意去怀疑我朋友的话直到朋友的爸爸说服我，我被骗了。

These lies that my friend and I told were nothing out of the ordinary for kids our age. Like learning to walk and talk, lying is something of a developmental milestone. While parents often find their children's lies troubling -- for they signal the beginning of a loss of innocence -- Kang Lee, a psychologist at the University of Toronto, sees the emergence of the behavior in toddlers as a reassuring sign that their cognitive growth is on track.

我和朋友说的这些谎在那个年龄段的孩子身上没什么特别。就像学习说话和走路一样，说谎是一个发展式的里程碑。父母经常为孩子的谎言感到不安，认为谎言是丧失无辜纯真的信号。多伦多大学的心理学家坎·李则认为，幼儿说谎行为的出现是令人放心的迹象，表明他们的认知增长正在进行中。
