Option 1:
Some people say "what you see is what you get" (meaning what you look like is what you are) while others say "never judge a book by its cover" (meaning outward appearances don't reflect what is inside the person). Discuss the implications of both attitudes and say which you agree with more.

We, humans, are very social animals, and mostly need social life to communicate ourself through language. This implies to know many people throughout life and so their differences.

Diversity and subjectivity are more present than similarity in our world, however, we have some psychological representations based in our experience of that we usually approve or disapprove (which is natural), so in the moment we meet someone, a person can cause us prejudices in a first instance, but depend in us to let the surprise item take place.

People always have something to us to learn, even if they don't know how to, so if we think always that "what you see is what you get", we are losing opportunities to learn to hear, to talk, to meet new realities, or simply to know what we reflect in others.

Although sometimes our first impression and our intuition in cooperation with prior knowledge can specify or associate some aspects with qualities of another person, we almost always have the opportunity to know him/her in depth.

In conclusion, we can naturally or unconsciously judge a book by its cover, but diversity can give us pretty much surprises, so if in some case we are meeting someone, we have to consider that he o she can be an interesting person, and that we can surprise others too.
