I've been in two minds about what to say, either go down the 'i really want to be friends so let's get lashed again next week' or just say 'oops sorry, it seems I do fancy you after all.'
The problem with the first options is it's a little thingy (I can't think of the word!) - I'm not being honest about the fact i fancy her so it might come back to bite me on the bum.
The problem with the second is she might go 'aaaaaaaaaargh!' and that will be the last I hear from her...
