Do you always travel with the same circle of friends, clones of yourself, a "family" that reassures your narcisso-esthetic choice? Or, are you versatile in your friendships, which are as intense as they are brief -- you're stuck for three months with one ("He's a genius! He's going to be the biggest artist of his generation."), then with another ("I never met a girl that bright."), then drop them both like yesterday's garbage?
