After a long trek to find a laundry café, only to find it had closed down, I sat in the window of a beautiful but washing-machine-free café near where the old one was. After a bit of time I noticed people were coming up to a tree that was outside the window and they seemed to be taking books from it. Sure enough - it’s a ‘lending tree’ of some sort where you pop along, have a look at what books are lying in the carved, weather-proof shelves in the wood, take any you want to read and leave any you wish for others to borrow. In Dublin it would be vandalised, in Copenhagen it would be ignored but here in Berlin it was working well with people stopping every 5 minutes to get involved. I would have waited for someone to be in the picture but it was raining and I had dirty socks to wash.
