What Can Be Seen in the Outside (a composition)

This is another composition written by my niece. Is it okay? How can it be improved? We're not native speakers of English. Thank you.

What Can Be Seen in the Outside

‘Don’t judge the book by its cover.’ Such a worn-out expression refers to the way we describe other people. We give comments based on their physical traits. What we see in them is what we call our ‘first impression.’

More often than not, we focus on what can be seen in the outside, don’t we? We’re contented with this. We don’t want to explore anymore.

Unless we hold a coconut (or anything else) in front of a mirror, we see only one side of it anyway. We’re contented with the green, fresh-looking side of it. We don’t want to further examine the fruit. But if we flip it onto the other side, we can say what really it is.

When we give comments, we don’t think much why a person is like that. We should always remember that there’s a reason why something happens or why someone acts that way.

We can try to ask somebody, ‘Why are you like that?’ By giving him or her a chance to explain, we can know the true reason behind what’s unseen.

What the book contains matters.
