My friend and I were walking down a street when I noticed a 1 yen coin on the sidewalk. I pointed at it and picked it up thinking it was a lucky find.
Three steps later my friend stopped. She said she’d prefer to put it back, and explained how in Japan they believe that when someone loses something it’s possible they will come back looking for it, so nobody takes anything that doesn’t belong to them. Not even a cent someone dropped on the street.
I felt embarrassed and immediately put it back.
