You really should just keep it professional regardless. With your words and actions. Keep the convo light, casually, professionally amicable... don't return touches (women can get away with that and do it often) and try to stay out of close quarters with them without a witness present. That's not always possible, but just best practice. And when you are in close quarters, say excuse me... or ask her to get that file, get that chart or whatever item she's obstructing with her body. And keep ya eyes above the neck, even if she tries to pull that okie doke shyt by opening or closing her blouse to redirect your eyes downward. Don't be food outchea, homie.
I mean...what you trying to talk with these work chix about if it isn't work related and/or wtf is the office is ordering for lunch?
Especially if you're working in one of these new age, black rimmed glasses Macbook dominant offices that's higher profile.
