Yesterday my Uber driver, who was wearing an N95 mask, explained to me that he was just getting over a bad cold but didn't want his customers to worry.
Today, waiting for an elevator, a masked elderly gentleman told me that it would be best if I took another elevator. "I don't know what I have but no need to get it, if you don't mind taking another elevator."
Today I am appreciating the kindness of these strangers who are looking out for those who don't even know them.
