Assumptions.

We all have them.
We all think our assumptions are right.
It's how we were built to think.
One of the many flaws of being human.
Assuming.
Assuming we know everything there is to know about a particular subject.
When we assume, or at least when I do, I don't take the time to find out if it's really true or not.
And neither do you.
Neither does anyone.
Whether you think you do or not, you DON'T.
No one does.
We just "know" were right.

However, most of the time, our assumptions are WRONG.

And I'll admit it.
