What do you get when you (a) crank up the heating because it's so cold outside, (b) still not sleeping well, (c) leave your laptop charging up in the other room, and (d) decide to try to watch some of the Australian Open tennis? Answer - you quickly fall asleep on the sofa having not written anything in your blog, groggily retreat upstairs to bed sometime after 2 am, and then make this half-hearted attempt to write something coherent before trying to get at least a few hours of decent sleep.
