A popular meme on Twitter shows a corona self-test and a red wooden pencil with which someone draws a second line below the control line – turning a negative test into a positive one. It’s the perfect excuse for almost any occasion: don’t feel like going to the office party? The fourth family celebration in a month? A date, even though it’s just so cozy in the hammock on the balcony? If the Covid-19 test is positive, nobody will ask.
