you see only what you want

It's true that when you ask to someone a question, not every time you get the response that you wished to get.
Why?
It's simple and is the humans nature.
For example when you ask to someone to define a animal ex: What is a dog?
The answer that you'll get is diferrent from all the persons that you will ask.
BUT the only answer that you'll like is the one you consider is true.
...i know tha mybe all I write has no sense........
........but my point is that when you tell to someone a fact you have to tell him what he want to hear from you. All other things are quikly forgoten.
