Today’ｓ incident ! Today, I was walking an aisle in the subwsay and I was talked by a foreign woman. I am Japanese. So I surely thought she will speak English. That's why I carefully heard what she said. However, I couldn't catch that. I thought "oh my gosh..." . But I elaborately heard one more again. Then, she spoke Japanese LOL. This a little international exchange is the most interesting in my incidents of a week.
