I never did, i don't think any of us did. One of us ended up in close proximity however to someone who'd tested positive for covid, just prior to getting the results of their tests. This person did not get sick.

That may or may not mean something or nothing, it's impossible to say. It's just an observation and nothing should be made of it unless that person were to ever be tested properly for anti-bodies and even then, you still can't draw any conclusions from it.

Myself at least, I never got sick through the rest of 2020, just followed the rules and such and didn't worry much, not because I thought I already had it, but mostly because there's no point in worrying about something I can't change. If I ended up with it after still doing the best I could to avoid situations that bring me into contact with it, then there's not much I can do except deal with it if it happened.

I figured being tested when not showing symptoms and having been following the rules fairly stringently would unnecessarily put myself in a situation and environment where I could be exposed for no real reason.
