Oh
no Sir, Mr. Partisan, excuUuse
meEe, I sure don't know who I am. OK?
Hum... according to some theory it is more important for us to adjust ourselves in function of what we think (counsciously and, moreover, uncounsciously) is our survival than to the objective reality, so our 5 senses and our brain detect and process the information accordingly. And they adjust with the changing reality all the time.
I just do the parrot, I'm not the creator of this theory, please do not shoot the messenger.
