Complicated and Scream Nothing is more complicated than our human beings in this universe.Men are different between one and another.What's more, how brilliant brains they have that they will be thinking over something ,which may also make them grow up and get mature. However,the biggest problem is that they will get changed as the environment does that they live in,which makes it more unpredictable of a man. Just like a couple of lovers .When they break up , they'll say "If never have we met each other，there‘ll be no so much of loneliness coming to me". This is such a big irony.
