i don't know why only when my mood is terribly bad now i find i want to type some words on my blog.May be this is the world anybody never ever knows me.Maybe on only this fictious world can i find myself.i dont know myself enough.sometime i just try to exhaust all my energy and then lie down on my basketball ground dazing in the sky .i just want to lost myself.but i work hard everyday.may be its just follow others' life way.other people study and i study,then other people get married and i do the same thing.perhaps its life.i don't know why i dont upload my blog when i am delighted.why don't i share my happiness to others? bear it in mind.
