Your friends' happiness and success is your happiness and your success. Your friends' awkwardness is your awkwardness. You share comfort. You have precisely one sense of confusion, and one sense of disgust, between you.
Not actually, not on the smallest of time scales. You aren't a hive mind. But this is what friendship means. You care about them, and they care about you. The sympathy is so automatic and complete that you'd treat them how you'd like to be treated – purely, from your heart.
