My sister and I regularly walked to the corner store and filled bags of penny candies. Once, when I realized the owner no longer bothered counting our bounty, I added an extra 10ยข or so worth of candies and lied about the number. I felt guilty for years afterwards!
I once stole a bow from Hallmark. I felt so bad about it that a couple weeks later I left what the bow would have cost on the counter while no one was looking.
I went through a period of rebellion when I was 16. I stole things like makeup, nail polish, dog clothing, decorative things for my fish bowl, and other random little things.
I seriously have to wonder how I never got caught. One day I stole a 2 pound bag of aquarium gravel, a 5"x4"x4" aquarium ornament, and a 5"x3.5"x3.5" aquarium ornament. I know it had to have been obvious. I don't know why I didn't just pay the $20. It's not like I couldn't afford it.
