he cried

As usual, when he saw me, he'll ask for "a,a,a" song.
As usual, I always delay what he wants.
"ok, we'll go after JW done her writing."
"ok."
While JW was doing her works, I went to washroom. But I only informed JW.
...
When I backed to the class... I can see his tears.
Poor lil CY, must has been beaten by teacher.
JW told me that he tried to go out of the class, that's why teacher bit him.

Later when I ask him in person, "Why u cried? Were you looking for me?"
"Yes." he said. But he had no more tears at the time.
