THERE ARE TWO KINDS OF PEOPLE;

There who people who tell the truth, and those who lie. These two people don't mix very well.

There are people who will seek psychiatric help and those who never will. Never the twain shall meet.

There are people who do not have the capacity to be empathic. This is a brain thing, and affects more people than we imagine.

There are people who have absolutely no self-perception. They have no idea who they are, what they want to do, or how others perceive them.

Some listen, others don't. Etc, on and on.

I think it helps to think in simple terms, although there are many more complexities than there is time.

I learned all this from Shakespeare, in the lines;

Listen more than you speak.
