Returns with big grin. There is so much I love about this! I adore their first, tentative approaches and Firenze's concern about falling for the wrong gender as well as wrong species. And Firenze teaching Rubeus about wanking, and Rubeus learning the proper animal way to show submission. I like the way you set them up, as two orphans and outcasts, to understand and support each other, making the source of their rapport clear to the reader. And Rubeus loving centaurs because they are human AND animal (it's two mints in one!), that's wonderfully typical. I totally enjoyed this relationship and all the neat things you put in it. I'm going to read it again, right now.
And -- how did you know I sent my kids to Hogwarts?
