A desirable behaviour. Going out of your way to avoid being close to people. In the olden days (prior to the COVID19-era), it would have been seen as rude to cross the street to avoid being close to a person. There was a risk that you’d be perceived as a snob, or as a racist, or intolerant in some way of the person you were avoiding. However, in the COVID19-era and beyond, it is the best thing you can do! And it’s a bonus that no one can accuse you of being rude.
I was on my morning walk to keep me sane during the “self-isolation” period when I saw Chatty Cathy walking towards me. I crossed the street. At first, she looked a bit sad but then I hollered “it’s not you, it’s just that I’m virus dodging!”
