DIt is the morning of February 2022. The coffee machine rumbles. The white check bar on the dining table determines whether it is an office day or not. Nice to have a quick test, you think. Tell the home inspector if you are infected with the latest virus. In two minutes, moreover.
The column in the test column gives the green light. A sigh and a cup of quick coffee. You bring the negative test to show the boss that you are free of infections.
