PL’s mum is helping out for this month (or possibly longer) – the traditional “confinement” month after a birth.
So we were having dinner – the three of us – and PL’s mum brought up the old superstition (or threat) about how children were told to clean their plates, otherwise for every bit of rice or leftovers on their plate would be a blemish or pimple on their future spouse face. So “clean up your plate or you’ll marry someone ugly!”
So I told PL, “see? because I cleaned my plate when I was a child, you are so pretty. Why didn’t you clean your plate when you were a child? Look at me now! Ugly!”
So beside using the old saw to threaten your children, you can also use it to beat up your spouse.
