Someone showed me this a few days ago. And while I'm not really into this style of poetry, I'm definitely into the message. It expresses a lot of things that I've been thinking about lately, but from a different angle - a woman's angle.
This is a result of a generation of boys who don't want to grow up. For the guy's point of view, the first part of the poem is what not to be. But her beautiful description of "you" is an incredible challenge of what we are to be.
I hope that this is an encouragement to you.
