I was in my second year of living in Seoul. I thought I was a real expert in Korean etiquette (礼仪) and culture.
I knew that I had to push gently onto the subway cars. I knew that I shouldn’t make eye contact with people. I knew that blowing my nose loudly “American style” was very rude. And I knew that I shouldn’t talk to people on the subway. Actually, that was not a p_________ to me because my Korean was really poor and I wouldn’t speak to anyone on the subway.
But one day, I was riding home from work on the subway, and I remembered that I needed to call a friend about meeting for dinner.
I took out my cell phone and called her. Of course, if you are familiar with the subway in Seoul, you know that there are s_________ everywhere showing no talking on cell phones. But I noticed that many passengers used their phones on the subway. I thought that the ‘no cell phones’ rule in Korea was like the ‘no food’ rule on the New York City subway. It’s a rule, but no one f_________ it.
While I was talking, other passengers looked at me sideways (侧着) like Korean people do when they think you are being rude. But one elderly woman looked s_________ at me and shook her head.
I finished my conversation, and I got off the train. I was very confused. Korean people use their phones. Why can’t I do the same? I asked m______.
Later that evening, I told my friend about the experience. She smiled and said, “The others are all text messaging or playing games on their phones. Sometimes they c_________ their voicemail. Sometimes they whisper a very short message to someone on a cell phone. But they never have whole conversations on their phones on the subway.”
I felt e_________ after hearing it. I still had a lot to learn. Even though I knew a lot of Korean habits, I was still American.
