my American coworker tests positive

As with my Korean coworker, who tested positive for COVID a while back and had to spend two weeks out of the office, my American coworker has now also tested positive for COVID. Like my Korean coworker, my American coworker also has a daughter who caught COVID through school (pre-school, in this case; she's three). 

From what I heard, Mom and daughter both began feeling under the weather after the girl brought the bug home; they got tested, ended up with positive results, and then my coworker called in to say he'd also tested positive. I don't know which COVID variant is at play, here; I hope it's omicron. I do know, though, that my coworker had gotten inoculated a while back, which goes to show that these shots mean next to nothing. They don't protect you from infection, and they don't stop you from infecting others. So what good are they, really?

Upshot: our office might be spending two weeks without our coworker unless the five-day isolation policy also applies to those who've been confirmed infected. The office will be a lot quieter without him; he's quite a talker. I tend to be a man of few words, in the office, unless you get me onto a topic I'm interested in. Gonna be boring for my boss, who also likes to talk.

Part of my brain feels as if the walls are closing in, and it's only a matter of time before I get infected. But thus far, I seem to have remained virus-free; either that, or I'm enjoying immunity after having been infected some time ago without experiencing any COVID symptoms. I honestly don't know what's up. Over the past two years, I've been nose-swabbed twice (or head-raped, as I like to say), and both times, I was negative. I keep hoping I do catch omicron and get this shit over with; natural immunity is supposedly a lot better than immunity-by-inoculation.
