When I said we'd test Zoë, Alexander, and Benjamin "eventually," what I meant was that we'd test them today. And because the tests came in a 4-pack I decided that I would take a test, too (though I had little hope it would be negative).
Zoë and Alexander tested first and were overjoyed when their tests both showed they were negative. Alexander ran around the house cheering for several minutes. Everyone was very aware that he was now negative.
I took my test a little later and was surprised when I didn't see a positive line creep up right away. After waiting the allotted amount of time it was still negative. I began to suspect the tests were faulty (because I'm trusting like that).
Fortunately (or not?), Benjamin's test showed that he was positive for COVID still.
He took the news with a shrug of his shoulders and a little, "Oh, well," but later began wailing dramatically, "Why did I have to get sick last?! Now I'm the only one left!" I don't think he was truly upset about it; he just gets dramatic sometimes.
Alexander does as well. He had been absolutely jubilant about testing negative, but soon became quite paranoid about having to continue sharing a room with Benjamin, who is still testing positive.
I explained all about antibodies to him (which he pronounces "anti-botties"), about how he won't have long-term immunity from COVID because it's constantly evolving but that his body is really good at fighting off this particular strain that we have right now. His antibodies know just what to do for COVID right now, so even though Benjamin is still breathing out virus particles, Alexander has little to worry about. His antibodies will take care of everything.
