Damn, raml - that were rough. Least you had the strength and courage to get out, thankfully. Nicely done!
I think petty evil is the worst. Everyone can be mean or nasty or thoughtless at times, sure, we're people. But petty evil is something you feel silly complaining about. It seems so small and insignificant. The guy is not going out and committing genocide, he's just verbally abusing you for not putting the plates in the right order in the draining rack.
It's like a steady, relentless drip of water. I do sometimes wonder how many people who "just snapped" one day were the victims of this petty evil.
