Self-isolation, in other words, quarantine, if you’ve just come off a plane, or you might’ve come in contact with somebody with COVID-19, means just that. You don’t go out, you stay at home, you stay in a room. You’ve got your own towel, your own utensils to eat, and people bring you your food. A bit of a challenge when you’re living alone. And it means you don’t take the rubbish out, in case you meet somebody else. You stay at home.
