He's just a common thief; scum in other words. I don't know why but I can't stand thieves. It's the cowardice of their actions, the way they do things. I don't like Robbers but at least they're upfront about it.
My girlfriend got her bike stolen last week from inside our block of flats, probably due to eejits leaving the main door on the latch for reasons unknown. There's just that awful feeling where you start to doubt your memory - maybe I locked the bike up at work, maybe it's over my parents - etc, before reason kicks in and you start feeling angry and totally frustrated. Then you ring the police who really don't care as they probably get hundreds of calls like this and never find the bikes. And then you have to buy a new bike and worry that it'll get nicked too.
Grrrrrrrrrrrr.
