LOVE IT!!
It is very good. Also it is very nice to write a friend a poem for their birthday or anytime.

A beautiful and heartfelt write for a friend so dear.... I have a friend that I feel the same way about, we are sisters at heart. I do think she'll like this very much.

This is really nice. I'm kind of a grammar freak though and 'your' should be 'you're' but other than that, its very good.
