Driven by thirst, I eyed a fine icicle outside the window, within hand's reach. I opened the window and broke off the icicle but at once a large, heavy guard prowling outside brutally snatched it away from me. "Warum?" I asked him in my poor German. "Hier ist kein warum," (there is no why here), he replied, pushing me inside with a shove.
