HELP ME TO CORRECT PLEASE:<why it="" is="" unwise="" to="" jump="" conclusions="" upon="" seeing="" or="" hearing="" something=""></why>

We are always saying what we saw see is true. However, times are changing. Just a simple piece of software----photoshop -- can break the rules without any difficulty. For example, when you are surprised by those seen what seem like reliable records of deals in Taobao and decided to buy something in there, you might were be being cheated by those vendors' vandor's excellent PS ability. So, it is unwise to jump to conclusions upon seeing or hearing something.
Sometimes, what we see or hear is not true, even it they looks like so it is official. Our technology has developed into a high level. Some visual and audio equipments puzzled us. And some things were maybe just were parts of what you saw or heard, which were fragmentary, and not objective. If you made a decision or acted immediately, you might have led things to go worse.
Use your imagination, and suppose you break end a relationship with your friend only because you heard or saw something bad but it was particularly about him or her. How inadvisable is it? So next time, before you start to judge, clear your mind first.
