People systematically underestimate the danger of catching Covid-19 from friends.

A group of many strangers is more dangerous than a group of a few friends, simply because the latter group is fewer. It is safer to eat at home with a few friends than in a restaurant with those friends plus many strangers. But even at home you should take precautions: set up a current of fresh air (strong enough you can feel it a little) through the dining room, sit far apart, and keep distance from each other whenever you don't have your N95 mask on.
