People are roasting each other at parties at work events around the fire. It's so fun. People are busting each other's chops and it's a sign of affection truly. It's a true test of love and friendship: can you make a man laugh at himself? So what makes a good burn? Go after targets you love and respect. And hit 'em hard.
People break down after a couple of hours. All the defenses go down and there's a kind of communication that if I spent 20 years in a living room with one of these people I would never never know as much about them as I do in that one day.
