I finally did it. I wore one of those masks because I caught a cold. Actually, not a cold, but a vicious stomach virus. But I couldn't help wondering: Who dunnit? Who didn't wear a surgical mask and passed their virus on to me?

Could it have been that night we all ate nabe and put our chopsticks into the same pot? Hmmm.

According to my Japanese doctor friends, catching something from everyone dipping their chopsticks into the same pot is remote as most colds are transferred via airborne substances.
