I think that childhood is the happiest time in people's life. Child's life is very interesting. A child lives in his small world full of dreams and adventures. He believes that Father Christmas with Snow Maiden bring presents in New Year. Heroes from favorite stories become his best friends. In childhood we don't realize what problems we could meet in maturity. But in childhood we don't understand that this time is happiest. When we are children we want to be adults. And when we are adults we want to come back in that carefree time although for a day. I think that we can be happy at any age particularly when we remember our childhood.
