Because if you want me to "act professional", I can tell you that I'm
not interested. I'm sitting in my home office wearign a bathrobe. The
same way I'm not going to start wearing ties, I'm *also* not going to
buy into the fake politeness, the lying, the office politics and
backstabbing, the passive aggressiveness, and the buzzwords. Because
THAT is what "acting professionally" results in: people resort to all
kinds of really nasty things because they are forced to act out their
normal urges in unnatural ways.
And please bring up "cultural sensitivity" while at it. And I'll give you back that same "cultural sensitivity". Please be sensitive to _my_ culture too.
