They are Nothing, but think they are Everything

This makes me sound like a antisocial freak, I know. But I intend it as a plain description of fact - this is the way most people are.

And the rest of us, who can see what is going on - have to take this into account.

The practical consequences are far-reaching. When I email with my siblings, for example, I have to take into account, that they will distort the facts to suit themselves. And not get too upset about this.
