When I go to a Walmart, rarely now because I find delivery a time, back, and money saver, there are noticeably fewer people. They don't seem any stranger than ever, though. This weekend at the opposite end of the social world, a nice resort area, things looked pretty normal. I also feel a little polluted after exposure to crowds. My solution is like any allergen exposure, take a shower, wash hair and clothes and nose. Do it after work, not before.
