“In this family, there’s a mother, a father, a grandma, and an older brother, and a daughter. And they’re eating pears. And what you’re supposed to do, like you can never split a pear. You can only eat a full pear. And I actually remember, fairly recently, I asked my mom if she wanted to split a pear, and she wouldn’t. The story started off with the littlest child gets the smallest pear. It’s about filial piety. The elders get the best pears. And you also can’t split pears. Because that splits your relationships with people. Keeping the pear together keeps the family together.”
There are two different stories going on here: a tale about a family who gets differently sized pears depending on age, and a folk belief that it is bad luck to split a pear. My informant told them so that they were interconnected. The story of the family eating pears is related to filial piety – the head of the house gets the biggest pear because he deserves the most respect, and the size of the fruit diminishes until the youngest child has the smallest pear.
When viewed in this light, the belief that splitting pears with someone is bad luck makes perfect sense. If a pear represents filial piety and the relationships between family members, splitting it would be terrible for the family.
