If you live by yourself, is it okay to drink milk directly from the carton? Can you dip to infinity or eat scoops of cookie dough batter using the mixing spoon? Do you say excuse me if you fart or I’m sorry if you snore? Somehow, it feels important to keep up certain expectations of etiquette, even if there is no one to observe or hear you. The only thing I’ve found that I’m perfectly unself-conscious about is going back for seconds…in fact I usually just double up on the firsts!
