What are your expectations for marriage? For citizens? For students? Bring it closer to home. What are your expectations for your spouse, for your children? Or, do you tell them, "I have no expectations for you, do as you please?"
I substitute teach. There is a significant difference between walking into a classroom where their teacher has high expectations and a classroom where the teacher has low expectations. I avoid the latter as much as possible as it is always chaotic.
We do society no favors by dismissing the behavior of others with a shrug. Expectations are the very least we can have of others.
