I papped myself!

I'm sitting here at the train station waiting for my 17:18 (of course I missed the 16:18 again), with the adreneline still pumping slightly from the scare I had about an hour ago.

I was sitting at my desk (on the ground floor of a very tall building) when suddenly there was a really loud explosion which shook the windows. A few yelps when out from people around me and everyone jumped up, like me, fearing the worst. Turned out it was a tyre exploding on a Lorry outside.
