One more: greeting people. I've had versions of this discussion with a few members of this list over the years, but it was (then) an issue of etiquette, rather than epidemiology. The world is different now.
To hug or not to hug? In this context, I interact with three kinds of friends, First, where hugging is just a polite hello. Second, where it is reserved for close friends. Third, where it is mildly or not-so-mildly discouraged. That was then. Now, even before the lockdown, my last F2F meeting was a couple of weeks ago - and we gave each other knowing grins and waved.
