Clearly you do not have a child I think, because a man becomes a man (what a sexist language!) only after he learnt a need to sacrifice. (Map corrected her speling) [ August 06, 2002: Message edited by: Mapraputa Is ]
It came from a beautful poem. I guess it's trying to express how it feels to look at the world with childlike wonder, and the poet is expressing his approval. I like this one better, though of course Wordworth's poem is more sublime.
