It took me about half an hour of the constant noise to make me realise something was wrong. Logging on to BBC's website, I quickly found out that it was due to a series of Tube 'explosions' on the London Underground.
But the enormity of the situation didn't sink in until we had reports of an explosion on a bus in Tavistock Square. That really gave me a chill.
You see, Tavistock Square is ten minutes walk from where I am.
Now they're talking about more blasts and terrorist attacks taking advantage of the timing, right after London Olympics bid.
So yes, it's kinda freaky to be living where I am right now.
