Yes, thank goodness my kids are all sweet souls. This one especially. He should be fine unless one of his closer coworkers has contracted it already and exposed him - the identified case works in the deli of the grocery store and he works stocking shelves, so they would only have fairly fleeting contacts in the break room and at the time cards. And he's pretty good about wearing his mask when other people are close. He's already gone to get his test.
But I was very proud of him, he had already figured out the steps to protect us in the house while he waits for his results. It's actually surprising that this is the first time he's had to get tested, even though he's worked all through the pandemic. And I'm sure glad that CMM got his booster shot two weeks ago.
