I remember a time in a class on a cold winter morning a Japanese girl came with a surgical mask & I thought, “Wow, people would go to extremes NOT to get sick in Japan.” Afterwards on a break I approached her & asked in a cynical manner: Why the mask? Are you afraid of catching a cold? And then she said, “In Japan you use it when YOU are under the weather & you don’t want other people to get sick. It is the polite thing to do.” Wow! That's a lesson I will never forget.
