some oddities in the neighbourhood

It was like a horror movie. Mr Urbano was watching the Globe from his window and spotted something strange on the roof ( and have a look at the sky!). Well, next day Mr Urbano realized that it was just Art. Nothing to worry about. Waiting for the bus, he made a framed self portrait with the digi compact. But, what's that on the pavement, ruining the masterpiece! What's that thing?

OK, the worst is still to come. A man in white on the roof! Looking like the guys who came to get E.T. Really scary. Men on roofs should be dressed in black.
