When I was a kid, I didn't receive an allowance. However, there always seemed to be about 45 cents in spare change I could scrape together between the cushions of the sofa in our living room. I think candy bars were about 20 cents, so I'd have some spare change left over. My folks never seemed to ask me where I got the money, and I never told them. I figured if I did tell them, they'd be more careful about the change in their pockets and my money supply would run dry. It was definitely a "don't ask, don't tell" type of arrangement..
