First impression

I heard researchers do a experiment about first impression. There are 3 cases. 1, Two person whose eyes are covered talk each other. They don’t shake hands. 2, Two person whose eyes are covered shake hands. They don’t talk. 3, Two person whose eyes are covered neither talk nor shake hands. The case that give the person a good impression (warmth and trustworthy ) is 2. Situation 3 give the person a cold impression. It shows us that communication and skin ship is important to get along with. It is not good to decide a person on only first impression. We cannot know a person’s thinking and personality without talking. I think talking is vary important to know each other. It is connected with making peaceful world.
