Sad and beautiful...

*sniff* So sad. Real beauty.

What a story. They way you wrote it, I did not realize that Severus was a ghost until the end

Beautifully written. I really like the poetical style, with all the metaphors and comparisons and the way you let the reader believe anything but the truth until the end.
I'm curious though about when he taught Hermione how to fly...

Who has a better right to dance on those graves than he? Msazurka or Stomp?

Well--at least someone got around to burying him. One does wonder, you know. And if anyone has the right to dance on Dumbledore's grave, it's his chief victim (though Harry ought to try it, too, it'd do him no end of good).

Very nice.

Sniff and smile

This is lovely. I like Snape's irreverent behavior; it seems that he's making the most of his afterlife.

Lovely!
