You don’t go to parties to meet new people. Birthday parties, wedding receptions, staff holiday parties, or whatever—you party every once in a while. But when you go to an event, you probably don’t go with the goal of making new friends; you’d rather hang out with the people you already know. That’s because, like a pair of well-worn sneakers, your current friends feel good on you. They know your quirks, and you feel comfortable around them. Plus, making new friends would mean making small talk.
