Michael, why are the drapes open.

I can't imagine Kay getting ready for bed with the drapes open. Considering there are supposed to be security guards patroling the compound. So I can only assume that when she laid down they were closed. But how someone could get in there and open such a wide expanse of drapes without waking her is hard to believe. Yet she is surprised to see them open. Fredo did not know it would be a hit, he did not open the drapes. That line adds fuel to a fire that can't be put out.
