In favour of podiquette

Now that I have one, I feel quite justified in expressing my annoyance at other commuters iPod abuses.

Definition: podiquette noun: 1. unwritten code of acceptable behaviours when using an MP3 device, such as an iPod.

You, yes you, in the pristine unscuffed, unmarked baby-poo-coloured Caterpillar boots, you know who you are. You tapped loudly with both feet with no discernible rhythm (a generous description) all the way along the District line. You looked around you and mouthed obviously to the words, although you only knew a few of them. You jiggled your knees, stood up, walked around, sat down again, all the while trying to get someone to catch your eye. Make it stop.
