Something's going right

You may wonder why the hell I'm making this post at 5:18 in the morning. Well, I got back from work last night as sick as a dog and fell asleep straight away. I woke up about an hour ago but have so far been unsuccessful in getting back to sleep, so I thought I'd strum the guitar and crank up the compy. I then saw my dead iPod sitting on my desk. I remembered I was supposed to take it in for a warranty exchange a couple of days ago. I thought 'well, there is no harm in trying to charge it again'. I put it in its dock and paint me green and call me Gumby, the bloody thing started charging. As you could imagine I'm pretty chuffed about that! I'm also at a loss to explain why it didn't charge before, even when connected to my friend's proper charger. Weird.
