Pestering you, is he? Funny, that. Especially considering that he's been exceptionally chummy to me as of late. "Hey mate," this and "All right?" that.

I'm not sure there's any great mystery surrounding his behaviour, though. We're in competition with one another, and he's probably looking for any potential weaknesses he can exploit. I'm sorry that he's apparently latched on to you as one of those. He really ought to know that couples of "our standing" have all manner of reasons for being together. If you're worried about it, though, we can make sure that we're seen snogging in Hogsmeade tomorrow.
