Hi Stoo,

Unfortunately I won't be able to make it to London this weekend. I've left it until as late as possible just in case circumstances change, but as it stands at the moment I won't make it.
I was really looking forward to the weekend and meeting up with you lot, but alas it is not to be, at least not for the present. Fortunately, I haven't lost out on the hotel booking, as we were going to be staying with friends just outside. Nevermind, there's always next time...
Have fun,
Trevor.
