No. Hells freaking no. What you see online is almost exactly what you see in person. Worse in some ways. I’ve been accused of having very little restraint… see a moron, nail a moron. Sometimes, I epically fail at the whole diplomacy thing, choosing to instead go for the blatantly honest explain it in less than 5 minutes answer. Not always the best decision, I’ll admit. They’ll get over it.
ETA: Had to reread the question… it’s what I get for being half awake and writing LJ. My answer doesn’t look quite so contradictory now.
