Harry lets me in on a secret: guys are pretty nice to each other in public. Always greeting each other “hey boss” or nodding as they pass each other on the street. Women aren’t like that. I don’t mean that women are all back-stabbers or have it in for each other or whatnot. But in public, we don’t nod nobly at each other. Nor do we really need to, as that nod also means I mean you no violence.
