Describe a young joke

I remember when I was in the fourth grade of primary school, I had a husky at home. That afternoon, after school, sparerib soup was stewed at home, and Hal and I squatted at the door together and stammered. After I chewed the flesh and blood, the bones were conveniently fed to Hal. The second uncle in the village just came back from work and laughed loudly: You two look like sisters, haha. Erha looked up and nodded.
