My friends complain that I don't like to venture further than a 20 minutes away by foot from my Berlin neighborhood, the "Red Island" (because it's surrounded by train track trenches and reachable only over bridges, which working-class Communists in the 20s barricaded to keep the cops out) in Schöneberg (which means "Pretty Mountain", though there is no mountain here), if I can possibly avoid it. One reason is laziness. Here are some others.
