what are these unheard of sins you condemn so much - and like so well?

Another wander through my brain, in the endless search to figure out who I am... this time, using the Riso-Hudson Enneagram Type Indicator (RHETI) SAMPLE

From the website, with pertinent bits (to me, of course) in italics:
The Observer (the Five) Observers have a need for knowledge and are introverted, curious, analytical, and insightful.
Fives as Children Often

• spend a lot of time alone reading, making collections, and so on
• have a few special friends rather than many
• are very bright and curious and do well in school
• have independent minds and often question their parents and teachers
• watch events from a detached point of view, gathering information
• assume a poker face in order not to look afraid
• are sensitive; avoid interpersonal conflict
• feel intruded upon and controlled and/or ignored and neglected

How to Get Along with Me

• Be independent, not clingy.
• Speak in a straightforward and brief manner.
• I need time alone to process my feelings and thoughts.
• Remember that if I seem aloof, distant, or arrogant, it may be that I am feeling uncomfortable.
• Make me feel welcome, but not too intensely, or I might doubt your sincerity.
• If I become irritated when I have to repeat things, it may be because it was such an effort to get my thoughts out in the first place.
• Don't come on like a bulldozer.
• Help me to avoid my pet peeves: big parties, other people's loud music, overdone emotions, and intrusions on my privacy

What I Like About Being a Five

• standing back and viewing life objectively
• coming to a thorough understanding; perceiving causes and effects
• my sense of integrity: doing what I think is right and not being influenced by social pressure
• not being caught up in material possessions and status
• being calm in a crisis

What's Hard About Being a Five

• being slow to put my knowledge and insights out in the world
• feeling bad when I act defensive or like a know-it-all
• being pressured to be with people when I don't want to be
• watching others with better social skills, but less intelligence or technical skill, do better professionally
