According to “The Sociopath Next Door” one in ten is a sociopath. Many sociopaths are extroverts. Not all extroverts are sociopaths. The word needs fewer “studies” on stupid things like this and more $500,000 studies on why cats always, and I mean ALWAYS want to be in the bathroom with you. If anybody is interested Freepmail me and I’ll write up a proposal.
Cats like running water and the sound of it. They like toilet bowl water. They also double as their own personal solar collectors.
