Sheniu System: Call the Head Teacher Mother-In-Law at the Beginning

On the first day of high school, a boy noticed that the new class teacher was very beautiful, so he quickly told his female classmate: This teacher is too beautiful, it would be great to take him home as his wife. The female classmate not only ignored him, but also gave him a blank look. The boy felt embarrassed and dug his toes on the ground. In order to lighten the atmosphere, he hurriedly said, "How old do you think his child is?" The female classmate responded to 16 in seconds. The male classmate asked: How did you know? The female classmate said: Because she is my mother. Years later, whenever a male classmate told his wife about this, the mother-in-law would laugh for a long time.
