Rising Sun for the evening

I went to London to meet with my ex-colleagues. Close to St. Paul's there is a Thai Restaurant, it is part of the Rising Sun public house. We were set to meet at 7pm, and had a good meal. It was great to catch up with them. I arrived in London very early and read through one of the free magazines - 'Sport'. Too much on golf for my liking, but the article on cycling was interesting, and there was a column on the Canadian GP that takes place this weekend. After that I wandered through the familiar roads, very little has changed. Opposite St Paul's, is the Tate Modern. As I glanced across, there was a painting on the side of the building. A man with a gun. Surely not, not in the middle of town. That might be dangerous. Supposing someone spots it out of the corner of his eye, just as I did. Supposing he is armed and reacts. Supposing he shoots at the building and kills someone in the line of fire.
I'm sorry, Tate Modern, but you'll just have to turn your building in-side-out. If you turn it back before the next general election, you will be arrested under the prevention of terrorism act.
