There seems to be two different meanings of the word 'expect' in common spoken English.

For example, 'I expect you to tidy your room this evening'. This is like a demand, in that the person speaking is asking someone to do something, and almost treat it like an order.

The second meaning is in a sentence like 'I expect it's going to rain tomorrow'. This isn't an order, merely relating what they think will happen in the future.

I don't believe either of the above examples would be ambiguous to a native speaker due to context, but the sentence 'I expect not to hear from you again' would be.

Is there a way to disambiguate this last use?
