"Now, Parkinson. You're supposed to be part of the nobility and it's clear you've missed a few lessons from the School of Hard Knocks as a result, so allow me to be your teacher. People can be broadly sorted into five broad types. There are the nice, also known as gullible idiots, who just want everyone to get along. You won't find any of them in Slytherin House. They almost always lose out in the end to the manipulative, which makes up the majority of this House. These are your liars, your schemers, your masterminds, as well as your two-bit frauds who happen to have a few spare brain cells to rub together." I heave out a sigh, annoyed just by thinking about people like that. Bluntness is so much easier to deal with, socially speaking.
