Am I really going on holiday tomorrow?

It's so strange, but I still can't believe I'm actually going on holiday tomorrow. I'm about to start packing (I've got the suitcase open on the bed), the holiday is planned out, I've done my research, yet the prospect of stepping onto a plane and getting off 6,000 miles later seems unreal. And it's going to be surreal leaving behind the predicted blizzard conditions of London and swapping them for the cloudless skies of Cape Town. Weird. Anyway, that suitcase isn't going to pack itself... better go.
