When I was a kid my parents controlled my account and would take money out of it sometimes, sometimes to punish me for this reason or that (staying up late sneaking SNL back when it was good, for instance.) What they didn’t control is the cash they didn’t see my grandparents slip me on my birthday, and therefore they couldn’t steal that. Sure “well they shouldn’t have done that in the first place,” but they did, or “you shouldn’t have disobeyed your parents,” ok whatever Mom, but I’m thankful I had my secret stash.
