I've been listening to various radio shows today, and will start to listen to the last HHGTG episode in a bit. Probably. Other than that, it's the whirr of three or four computer fans and the occasional whine from the cats.
But what I'm really listening to is the sound of my going up the wall as the local anaesthetic from my dentist's visit wears off and my gums itch and my teeth hurt. Aargh!
