Elle ________ Franck ne vienne pas. She's expecting Franck not to come.

Question

I answered this question with attends que and was marked wrong. In the notes on attendre que it  says "to wait for [someone] i.e. Frank to do [something] i.e. not to come" why is my answer wrong?

Hi Jeramy,
In simple terms -

attendre que = to  wait for something to happen ( just a question of time) 
s'attendre à ce que = to expect something to happen ( it's an expectation- something that might happen or might not

You could say -
Elle attend que Franck vienne = She is waiting for Franck to come 
You cannot 'wait' for someone not to come it has to be 'expect' in this case.
Elle s'attend à ce que Franck ne vienne pas = She's expecting Franck not to come 
Hope this helps!
