A neighbor just urged me to "Have a safe trip." I might be inclined to say that to someone flying into a war zone, but do we really need it for the Portland-Newark red-eye? For me, Have a safe trip" means "Hope you don't get killed." It focuses on the negative, to put it mildly. Am I being oversensitive, or are we a timorous, risk-obsessed culture? What ever happened to Bon Voyage and Happy Trails?
