20 years of harassment while I tried to be nice and cooperative teaches me that being nice doesn't work, being cooperative doesn't work, people still backstab, people won't value you if you help them, people don't value you if you're nice. Threats .. harassment .. bitching .. lying .. other deception .. false accusations ..
Now I'm pissed off and rude because that's how I have been treated for years, and now people complain that my behavior is "not good enough". Go figure.
