快乐的源头在何处

don't know what I do now is right, those are wrong, and when I finally Laosi when I know these. So I can do now is to try to do well in everything, and then wait to die a natural death.Sometimes I can be very happy to talk to everyone, can be very presumptuous, but no one knows, it is but very deliberatelycamouflage, camouflage; I can make him very happy very happy, but couldn't find the source of happiness, just giggle.
