Unpopular opinion: I think you should leave a found notebook where it is
I found a small, leather bound journal on a bench in a park in Portland about six months ago. It was clearly someone's personal diary, full of daily thoughts and sketches. Everyone online says to try and find the owner, but I just put it back under the bench and walked away. My feeling is that a diary is a private thing, and the person who lost it might come back looking for it. If I took it, even to try and return it, I'd be reading their private words, which feels wrong. It's not my story to find or to share. The book was dry and safe where it was. Has anyone else just left something personal alone, even when you knew you could maybe help?
