Aside, but on similar lines:

I have to keep reminding myself that everyone isn't like me.

In my private talks with myself, I refer to this skill as modelling other people well: in effect, I'm trying to build models for different kinds of people.

There's lots of different kinds, and a few broad types show up, explaining most of their (general / broad) actions.

This is still very much a work in progress for myself too, but would be very interesting to see if I get somewhere substantial.
