There is nothing wrong with expectations.
Expectations is a construct in which we build boundaries, create reliable systems and establish trust with our fellow man.
If there is a red light, there is an expectation that oncoming traffic will eventually stop.
If you work, there is an expectation that whether it be a week from now, two weeks from now and so on, you will be compensated.
If you check out a book at the library, the library expects for you to eventually return the book at some later time.
