Appearances can be deceptive, especially when a judgement is to be delivered on the basis of it. For example a poster of a movie may depict something completely different from what the movie may eventually convey to the person who watches it.

They also say that the first impression is the last impression, but what I have found in my experience is that the first impression(with reference to appearance) is never the best or most lasting impression.

Nice post, point well explained!
