Trying to find a shorter way home I decided to take the U7 all the way to Berliner strasse and catch the U9 to Birken strasse just a few stops down, but I miscounted swapping trains, jumped on the U6 when I should have stayed course on the U7, and had to jump back on the U6 to the Mehringdam stop.Waiting for the U7 to Rudow to catch the U8 at Hermannplatz then ride that to the U9 would have had a shorter wait time, but one more train. It is also what I usually do. But now, as I’m waiting and additional 7 minutes which drag on like hours for the U7 to Rathaus Spandeu, I’m quickly becoming impatient, and it’s become apparent that my Berliner strasse might be pat my street. I grit my teeth, waiting for the train. Upon checking the map, Berliner strasse is on the way, and while it may have less transfers, because of the wait, it could be just as long. The only difference it makes is if I want to take an extra train or not.
