Wall

I made this photo last Friday inside the Aachen Hauptbahnhof. I was standing there with my luggage waiting when I decided I wanted a photo of the wall I was looking at. I took out my camera, focussed on the wall across the tracks, made one or two photos then put my camera away. I noticed afterwards that I was getting many a "What-the-hell-are-you-doing?" stare from those around me. As I've discussed with another American colleague... We seem to get those all the time, everywhere in Germany, for no apparent reason at all. ::shrugs::
