You want everyone to like you- even those you barely know and will likely never see again.
The worst fear you have is being ostracized by society.
You can't bear the thought of being useless to society.
You are aware of the interpersonal politics going on even if you don't take part.
You were disappointed to find that there aren't too many threads dedicated to SO first.
When you are at a party you are instantly aware of the most powerful person in the room.
You are well of your social status in any group you partake in (including this forum).
You would rather have a large circle of acquaintances to draw upon than a few close-knit friends.
