There's a lot I could do with an hour - shower, do my hair, get my slap on (scaffolding?), walk the dog, go to the supermarket, etc etc - but I cannot bear to leave the machine unattended. My Mac has never given me a problem while burning DVDs - but even so - sod's law dictates that if I went to get in the shower you can guarantee that it would crash or some catastrophe would happen.
Talking of Sod's law - apparently (or so I'm reliably informed by somebody brainy who has a science degree) buttered toast doesn't always fall buttered side down....(it does in Tracy's World) ...according to science - it's quite random how it will fall!!! Fancy that!
