Adik tiri membuahkan hasil hutang sama abang tirinya dengan uang rela dientot habis-habisan.

My shy stepsister had her weekly allowance money taken away as punishment, so she doesn't have money to cover her school expenses. I lend her money and it's time to pay me that money, I collect it from her and she doesn't have the money to do it, so she pays me in kind.
