He who is passionate and hasty is generally honest. It is your cool, dissembling hypocrite of whom you should beware.

A quick temper is unpleasant but usually transparent. Someone who flares has told you exactly where they stand, and the outburst is over almost as fast as it started. The person to watch is the one who never loses composure while steadily arranging things in their own favour, because nothing they show you is unplanned. Loudness is a nuisance; calculated calm can be a good deal worse.

When you are deciding whom to trust, weight what people do over months above how pleasant they are in the room. Be wary of anyone whose surface never changes regardless of what is happening underneath.
