The first five minutes or even less is the most critical period in an encounter between two people is.
Let's face it: We judge others within the blink of an eye lid!

The first impressions formed in this time will tend to persist and even be reinforced by later behavior, which will tend to be interpreted not objectively but in the light of these first impressions.

We tend to note the occasions on which our first impressions of people were mistaken and had later to be revised because there are so few of them.
But in these first few minutes we do more than simply decide whether or not we like someone.
We make judgments about their character, personality, intelligence, temperament, habits, working abilities, suitability as a friend or lover, and so on.
All of this is done on the basis of very little information about the other.
