Is it that I can't appreciate Literature, has understanding problems or has a different point of view?

Two days ago was another boring literature lesson... Well that's how it went...

The teacher came in(speaking in an LinChuan-accent, you get what i mean right?)...

Teacher: Has everyone answered the questions that I gave you?
Class(to one another): Need to do?
Teacher(heard it): Of course! I shall give you 5 minutes to do as much as you can and we will go through the answers.

I looked at the questions... Didn't understand half of them... Why should I bother anyway? Thinking that I should drop literature at Sec 3. Few minutes later, the teacher spoke again...

Teacher: Now we shall go through the answers... You! Can you answer me what is the poem about?
Student A: It about how important friendship is.
Teacher: Since his answer is the same as mine, it is correct. Do corrections if yours is different.

What! It's about freedom! Well... sort of. I mean the obvious meaning is freedom. Friendship is hidden. Well I do see it does shows that friendship is important but who knows? What is simple but complicated? Is there such a thing? How can appreciate be considered as a mood? See why I can't appreciate it? I always stick to the truth, I mean I may wander off sometimes but what I say always have a possibility! Now basically that's all, although I feel that I can't quit due to the fact that the brainiacs won't.
