I'll start out with this beautiful memory:
I was about 20-21, and it was the night before a long journey. I had planned to stay away at least 6 months, maybe more. My first resort was Iceland, then I had planned to on to the Faroe Islands, and then work my way down to Scotland via the small groups of islands that are scattered along the way. (Shetland and Orkney for those of you who know the area. Good seacliff climbing.)
My flight was early in the morning, as and usual I was out in the last minute washing all my clothes. I didn't have a washing machine in my flat, but as always in Swedish houses, there is a common one in the cellar of the house. Very late at night I became exhausted and decided to sleep a few hours before getting all the laundry that was in the washing machines and dry tumbler. Unfortunately I overslept a bit, so I was in a real hurry when I rushed down to get my clothes - just to find they were all gone. All. Not even a sock left. Instead, someone else's laundry was washing. I checked the booking list, and found out it was my upstairs neighbour. I ran up the stairs and rang their doorbell. Nobody opened. Of course, it was a weekday, and they both worked. It was only minutes until I had to leave, so I could do nothing more than collect the few clothes I had left in a tiny sports bag (the kind you use when you go to the gym, a very small one) and ring for a cab...
Much later, I learned from the guy I rented my flat to while I was away, that my upstairs neighbours had taken my clothes by mistake. The guy had started their laundry in the morning, and then put all my clothes at a table beside. Then he went to work. When the woman came down later to fetch their laundry, she took for granted that all clothes were theirs, and simply brought it all back to their flat before going to her job.
