Chalk, for each person is familiar with the school, I am the chalk, have you ever thought of, in my this ordinary body, but contains a noble character.
Chalk: I can't compare with bright lights, also did not bring joy to your life, don't like the swallow of spring bring you joy, but my color can create a pleasing picture, write one to let a person enchanted, and draw on the blackboard clearly each geometry make people to understand, people who did not love me, write down the well, don't need, but no any attachment, all of a sudden I obliterated, but I don't feel sad, because this is my identity, pay only, without the need to return.
