Thats perfect! The poem was so scarily River-like and I loved it. You have a real knack for the whole poetry thing :)

And the story was very good too. The idea of her responding to his poem with one of her own and his whole reaction to that - it works, it really does.

Last line made me crack up. Its just so very Jayne. You have a real handle on these characters, and if you wanted to write a little more to this series, I don't think anyone would complain, I certainly wouldn't ;)
