One of the things which is kind of haunting me at the moment is how long it'll be before our behaviour goes back to normal, even when restrictions are relaxed. How long before we start embracing friends again, shaking an acquaintance's hand?

It's not the main thing. Easy to forget. But still terribly sad that we'll likely have this physical and mental separation between people for months to come, no matter what else changes. We might struggle to go back to the old way.
