Uneasy truce?
Now, what worries me is that last night, Kieran may have finally broken - at around 12.48 am I discovered the following note:

"Dear Sarah

Could you please drop off the key either under my door or in the Porters' Lodge when you've got a minute.

Cheers,
Kieran"

Now I suspect Kieran's had enough of the Strawberry, the room-rearrangement possibly being the last straw... oh dear. The key was, of course, duly returned. We'll see how this plays out.
