Don’t break a ‘pinkie promise’(123711)

为什么许诺要钩小手指？

Q: Why do people hook pinkies (用小指拉钩) to make a promise?

A: In China, children like to make promises by hooking pinkies with each other and saying: “A pinkie promise must be kept for 100 years.” Then, they may press their thumbs together to complete the promise. Sometimes, couples will hook pinkies and promise to be together forever.
