I think that if people are instructed about anything it should be about the nature of cruelty. And about why people behave so cruelly to each other. And what kind of satisfactions they derive from it. And why there is always a cost and a price to be paid.
It is utterly false and cruelly arbitrary to put all the play and learning into childhood all the work into middle age and all the regrets into old age.
I don't have expectations. Expectations in your life just lead to giant disappointments.
