Expectation is massively related to circumstances.
When you have a continuous and seemingly normal situation, it becomes the level at which you define 'ordinary'. Raise the bar few more levels and you have expectation. We are always expecting high, higher than what we commonly have.

Hence why expectation isn't comparable among people whose circumstances differ from each other. Why stretching our own condition and easily assuming people will submit to it? Our conditions differ, our ideals differ, why going by the same values? Sometimes we are getting waaay overboard which such self-centered way of thinking.
