First impression matters! First impression matters!! First impression matters, sounds like a broken record already. While it does matter, second, third, fourth and hundredth impression matters as well. How on earth are you supposed to know a complete human being, who has lived for more than a decade on earth in just about, 20 seconds? We loose great relationships if we write off people because of a first bad impression. Whereas, we only set ourselves up for a big disappointment when we hold high hopes in a person due to first good impression. While I'm not making light the fact that we need to be nice and be on our beat behavior while meeting someone for the first time, I think we should make allowances for people regardless of how we perceive them after a first meeting.
