Humans in general are judgemental. No matter what other people say, we all fall to prejudice. The moment you learn about the world, the moment you start to comprehend things, the moment you start to think, you start to label things.

When we are a three, we judge vegetables gross just because they don't look appetizing.

When we are five, we judge our teachers scary just because we're too young to understand their roles.

When we're seven, we start to choose our friends by judging people not being suitable to be at our sides.

At ten, we start to doubt ourselves so we doubt others too.

At twelve, we start to noticed everything so we judge everything too.

At fifteen, we all start to have insecurities so we find something wrong at other people too.

We all judge other people at one point. It's a natural instinct of a human being because none of us are content or satisfied until we are in the brink of our death. Hell, there's even a lof of people dying with regrets as big as China.

This is why people learn how to start guarding themselves. Putting walls as high as eiffel tower, as thick as ice berge, strong as diamond, and thorny as roses. It differs. From one person to another. We all have our walls, no matter how obvious or how it is not.
