Today, we have a birdbrain on campus who is always making a fool of himself. He is so foolish that he doesn't even realize that he is being laughed at by others. He thinks that he is cleverer than everyone else, but in reality, he is just a big joke.
On the other hand, we also have some students who are very intelligent and capable of achieving great things. They are able to think clearly and make wise decisions, which is why they are respected by their classmates and teachers.
In conclusion, we should not judge a person by their intelligence level, but rather by their character and behavior. We should respect everyone, regardless of their IQ level.
