My American in-laws are awful at it, they seem to think that it’s okay if you’re only seeing close friends or family etc (though I’m sure this is the shitty advice they’re getting from their government). Apparently my wife’s grandmother had a test for it a month back and it came out clean, and they acted like that meant she’d be fine to go hang out with other people or head off to her usual social routine - when it actually means she’s still totally at risk. Bizarre.
