What does it mean to be “lifelong friends”?  Well, Franny, Finn, Charlie and Sam bring literal meaning to the phrase.  They met one another within 48 hours of each other’s birth — a consequence of the close friendship of their parents, Mark, Jen, P.K. and Beth.  Now half a generation later, the Flackett-Levin family is off wandering the planet while the Colt-Simonds family has settled comfortably in Woods Hole, Massachusetts.  For one week in Paris (which flew by as if it were a day), the four young compatriots got the chance to pick up right where they left off, laughing, playing, creating shows — and we get a short meditation on the true meaning of “lifelong friendship” from four bonafide practitioners.
