     There are a lot of things that happen to me in China but would certainly never happen in the US. One of

those things is being called"strong".

     The first time was last December. I was walking across the high school campus in Guangzhou where I

taught when a student in a gray scarf waved hello. I smiled and waved back, but then she stopped and called

my name."You're so strong!" She smiled and pointed at what appeared to be my right arm.

     I looked down at my arms. Let's get one thing clear: I'm a very skinny guy. Once, while rehearsing for a

high school talent show, I was told by the teacher in charge that I couldn't participate in the men's shirtless

dance routine because my visible rib cage (胸腔) would frighten the audience.

     "I'm so what?""You're so strong!" she repeated."Um, thanks!" I didn't know what else to say, so we both

waved goodbye.

     The next morning I stepped into my oral English classroom only to be greeted instantly by a unanimous

(异口同声的) "Waaa!" of shock and admiration."What?" I asked."You're so strong!" shouted a boy from the

back of the class.

     "Okay, will someone tell me what that means?" I was curious as to the real reason for such praise. So I

turned to the monitor, gesturing for him to speak.

     "We just mean, you look very strong today," he offered earnestly.

     "What?! You mean like this?" I curled (卷起) my arm like a body-builder.

      "No! But it's so cold, and you're only wearing a short-sleeved shirt."

     Oh, I got it. My"strength" had less to do with my muscle and more to do with my apparent ignorance of

the cold weather.
