The teacher from Mars

Recently, all the kids in my class make me feel i'm a teacher from Mars.

In fact, i'm JUST eight or nine years older than those kids, which means the gap shouldn't be so HUGE!

But          Why?!

I found myself stuck or trapped.

I don't have a clue why they act like being not educated, or i should say so "innocent!"

Even passing the paper could be so noisy.

But only when i warned them, they could calm down.
