Rhinos are careful about the stories We tell our Tots. They are impressionable, and We’d rather impress them only once.
No Rhino story We can think of ends with “Happily Ever After”. Such a slogan leads to Expectations which will be unfulfilled. And those sorts of Expectations can be hard to shake.
We prefer something more realistic, like “and the next day was more Happy, or less Happy, or roughly, just as Happy”.
