“Hi ho”is another stylistic device, which is reminiscent of “zing” that follows a joke.
“I wish that people who are conventionally supposed to love each other would say to each other, when they fight, "Please — a little less love, and a little more common decency”
Funny and true. Why do people hurt the people they love? Why does being close to someone lead to treating each other worse than you would to someone you don’t know? Politeness could indeed improve relationships of those in love and/or close to each other.
