... when Pa Ingalls took care of a spoiled rich kid for a summer. The dad decided the kid needed to get some sort of a work ethic because the kid was lazy, so he left him with the Ingalls family (frankly, it was evident that the dad didn't want anything to do with the kid). When the dad came to get his son and bring him home at the end of the summer, it was clear he didn't really love the boy. Thinking they were alone, pa cornered the guy in the barn and said "You don't love your son. Admit it! say you don't love your son!". And the father blurts out "You're right, I don't love my son". Just then the kid is seen standing in the doorway and runs out crying. The father chases him and catches him in his arms and starts to cry too. Then pa walks in and he starts to cry. Haha.
