“the ability to work within groups.” From the book The Social Animal by David Brooks (quote from TED Talk by Brooks).
“a social affinity in which one person stands with another person, closely understanding his or her feelings. Also known as empathic concern, it is the feeling of compassion or concern for another, the wish to see them better off or happier…having a positive regard or a non-fleeting concern for the other person.” From Wikipedia.org.
