True. I'll share one experience from when I was like 6. My dad and my uncle had a joint supermarket. One day, in a new stock delivery, make up sets (the ones with little drawers for eye shadow, blush, a mirror, kajal etc) were bought to be sold in the store. My elder sister, three cousins and I chipped in our money and bought that make up set. We put the money in the cash register and took the make up set out secretly. We, then, hid the set underneath the couch and guess what? Within 3 hours, everyone knew that we had secretly purchased a make up set. We had to return the make up set back to the store at that same moment. Now that was a "kalakari" according to my parents and that was "resolved' the same time as it was found out.
The moral of this long-winded story is that in real life, kalakaries are exposed much faster and are acted upon immediately. In SNS, one kalakari takes such a long time--it's no wonder that nothing effects Rashi. With so much time between the kalakari's initiation and her "punishment", she loses sight of why she's been "punished". This kind of method is never effective for disciplining children.
