Oh, Merlin- yes, that one. Is it programmed into all Slytherins as part of some sort of induction ritual? Doesn't it get a bit tiring laughing like that?
I didn't do it on purpose! It was completely accidently, and I felt really bad because his jumper got wet, so I offered mine, but then he did this eyebrow waggle thing- like this- so I ran off to find Nicolas. Um.

'kay.
But how am I going to know if I'm using it on someone else?
