Actually, there was supposed to be a little epilogue section where Ron is visiting Harry and Neville in hospital, and Ron can't talk because he's laughing so hard, but I knew that if I wrote that, I just wouldn't be able to stop myself from writing more, and then there would be awkward handjobs while Neville's snoring in the next bed, and...
Stop, my mind, stop!
I was worried a bit for Hermione's scenes; I actually rewrote them several times to remove "creepiness". I commented either above or on my other story about the difficulty I have actually writing smut. I actually find it very easy to imagine, just so difficult to write without giggling my head off and having to do something else for a while.
