serendipity

my chinese compo (exam) today.
was a little difficult.
I chose the picture, I really have no idea of how to do the ming ti zuo wen.
Its about a boy, whom I named him; xiao ming.
and he threw a banna skin at the corridor.
then, a guy, I think his neighbour, was walking at the corridor, and he slipped.
next, a woman opened her house door, and above her head was a question mark.
next picture, that guy is sitting on a stool, and the woman is applying some medicine on his back, and that banana skin boy was telling him about what had happened.
so, that guy scolded him.
and then question mark.
I wrote; for the last paragraph that the man forgave the boy b'cos he did tell him that his the one who threw the banana skin.
yeah, stupid right?
