Last day in Berlin

My sense of direction is getting mixed up. Upon leaving a museum I started walking home. Then I (luckily) stopped for a rest. (I don’t want to kill my ankle again.) I looked at the apartments across the street and noticed the satellite dishes were pointed the wrong way. They should be facing the equator. Crud! I’m the one pointed the wrong way.
Then I got back to the hostel and went for a wander without a map. It ended poorly.
I miss the gird system.
Subways don’t help either. You come out of them with no idea which way you are facing. Berlin’s metro is still much better than Paris’ labyrinth. Each station was a two part maze. One maze to actually find the station. Another maze to find your train in the station. Berlin has non-cryptic signs to help you out.
I met my friend for lunch. I know him as a world famous DJ, but he does have a regular job. So lunch was all he had time for. He works right next to Checkpoint Charlie, so after I saw him off, I checked it out in more detail. I saw the Topography of Terror presentation on the Nazis. Then the museum on the wall.
It was all very depressing.
After the same roommates for two nights, the Brazilians have been replaced with a Peruvian and a Colombian and one of unknown origin. I don’t feel I can trust them. Especially when I returned to the room to find the door open and only a sleeping person to protect our belongings.
