what is right I always tell my kid what you can do, what you can't do. but sometimes, I was thinking , is that correctly? Do we really know what is right or not even if we are adults. Actually, the fact is we do not know. if we really know what is right, we will haven't war, disasters, homelessness. We even needn't elect , law and limited. the world will become more efficent and beautiful. but that is far more complex than what we can image. everything had happened because of the sense of worth. and the sense of worth base on our childhood's education and environment. So what we should teach our children.
