You did a lovely job on this fic! You kept it short and sweet (don't get me wrong, length is no bad thing, but this was just enough to keep you hooked) and the ending made me grin! What a cute little pairing!
I loved the way you handled this. Sirius and Minerva is not an easy pairing and you handled it beautifully. Sirius the romantic confronting Dumbledore was excellent. I would have loved to know what the look on the Headmaster's face was when Siruis left the office. Excellent!
Do you want to know the strangest thing? I was reading your fic, and I had a playlist of about 15 songs going. Just as Minerva and Sirius started dancing, Sinatra's "Strangers in the Night" started playing. I just cracked up at the irony of it... other than that, interesting story. Very cute. Liked the mini-confrontation with Dumbledore. The age difference - I believe you said she was 15 years older than he - doesn't quite seem right to me, but I'm not that concerned. I like your style and unlikely pairings. Ciao.
I just love the ending of this piece, And the fact that for once, an older woman gets a younger guy. It's usually the other way round, but I've found in real life I tend to pick boyfriends who are younger than me... perhaps I like the control aspect? lol. Anyway, considering the difficulty of this pairing, you've done really well! Spectacular, in fact! *applause*
