Almost-Dispassionate
When someone is completely neutral, indifferent, detached, and unruffled about everything, we say they are dispassionate. When someone's emotions get the better of them (when an idea grips the meat), we say that the person has become passionate. But almost-everyone spends almost-all their time being almost-dispassionate about almost-everything.
