Actually I hate mobile phones in any public space - let alone concerts! Anyone who fails to switch their phone off at a concert should be hung on a gibbet, somewhere near the stage, and left there as an object lesson to the rest!

Mobile phones should also be banned on public transport (as I believe they are in Japan). If anyone reading this is in the habit of conducting trivial conversations with your equally moronic mates, at the top of your voice, whilst travelling on the bus or train - be warned - I might be sitting behind you and the 'red mist' could come down and when it clears you could be lying in the aisle choking on your f*cking phone! Of course, I might have to spend some locked up in a 'secure institution' - but it would be worth it!!
