All my life, I never learned a single curse or swear word in my native Teochew language.
My grandfather only had one: ‘if you don’t stop misbehaving, I will make you eat a potato!’
It truly struck fear in him. To him, the worse parts of living through a war (the Japanese occupation) was how little rice he had and how many potatoes he had to eat instead. Oh, and his friends being disappeared, but mainly, having to eat potatoes.
