I found a lost card wallet in the street when I was on my way from the office to the tube station, right in the middle of the pavement. Bank card, driver’s license, everything. With a name and a date of birth, and the help of Sweden’s lax regulations about people’s personal information, I was able to find the person’s address online. It was roughly in the direction I would be going anyway, so I changed my travel plans slightly and headed that way. Meanwhile I tried to get hold of the person on social media. Found them on Facebook, sent a message, and got one back within ten minutes. They hadn’t even noticed the loss of the wallet. We agreed to meet up at the tube station nearest them, so that I could hand it back to them. I sent them this selfie so that they’d be able to find me. (I, of course, already had a photo of them, on their driver’s license.)
