Yes, we all know that being late (say, more than 20 minutes) is completely unacceptable when food is piping hot and on the table. What’s even worse, though, is showing up early in the frantic final moments when your host is trying not to burn the roast, chill the rosé, and select the right mood music (Nina Simone, obviously). The early bird does not catch the worm at dinner parties. Instead, they’re likely to instigate a serious pressure cooker situation for even the least anxious host. If you find yourself to be the first to arrive, get marching orders from your host, who will surely appreciate the gesture.
