I know it happens practically all the time in Iraq but somehow it's worse when it's somewhere you've visited, when it could be people you know.

I knew something had happened but the train stations only said to avoid travelling into London city centre due to disruptions to travel. The girl next to me on the train phoned her mom to tell her she was alright. There were huge traffic jams in Birmingham as police stopped buses and did random checks.

Of course it's worse when you're affected. It's selfish somehow how people switch away from the news when a new bomb blast happens in Iraq and stay riveted to TV screens when London is hit.
