I don't agree with such a view .
The first impression is very important in many occasions.Generally speaking ,the first impression does mean something .After all we cannot know a person very well this way.for people have different personalities.such as we haveto take much time to get to know people who are indrawn ,or we couldn't get the real result.on the other hand ,the first impression is changeable.that is the reason why i don't agree the view above.
