I just found out that if you go to a lost item in inventory it says investigate and you get a clue to who it belongs to. And that if you give it to the right villager on the first try you get a better reward(and more friendship points I think). You learn something new everyday with this game. I found a notebook with a pen and the clue said most of it is illegible but you can make out the word band. So how do you figure out who it belongs to? Thanks
