I was at a supermarket and saw a few people coughing.
In Japan, we wear a mask when it's really dry or you feel like you are catching cold.
I think it is because it is more condensed with population and people are so close to each other everywhere.
We not only try to avoid getting sick, but try not to spread the virus you have.
It is a courtesy and that is something everyone does there.
My mother of course was wearing one when she felt sick.
That was just a few weeks after we just moved here.
Yes, she was wearing it in California.
People were staring at her as if she was doing something weird.
She was wondering for a while why people were looking at her strangely.
