Can you please tell me what's the difference in meaning between expect someone to do something and be expecting someone to do something? For example:
The boss expects me to finish the project by Friday.
The boss is expecting me to finish the project by Friday.
I don't expect you to return the book right away.
I'm not expecting you to return the book right away.
I hear both used but can't figure out the slight difference in meaning and the contexts where one is used rather than the other. Unfortunately the grammar books I have don't answer the question.
