Hi Cornelia!! This is SO cool!! Such a great idea. I hope all is well and the office has calmed down after the concert chaos! It was a wonderful day, and I hope you had as much fun as I did. Tell everyone I said hi :)
No, not cliche because next year people won't even rememer she exists, hopefully. As for Berlin, The holocaust memorial for sure. I really just had a fun time walking around there. If you are biking, I would suggest stopping by the Kieren Cafe, it's a cool part of East Berlin and a very nice bike shop/cafe.
