Potioncat:
Good point. I think you're right. I don't think we know the real truth 
about Occlumency lessons. Harry was told why he was taking lessons, 
just like McG was told why baby Harry was being left with the Dursleys. 
Truth, but perhaps not the whole truth. And I've always thought Snape 
was in danger just by offering the lessons. We know he often does 
seemingly "mean" things for what turns out to be "good" reasons. Just 
like Crouch!Moody did "good" things for "bad" reasons; and this would 
fit that pattern.
 

Christelle found the site for Draco addressing Flitwick as Professor. 
And I found the section where McG caught Draco and the others out after 
midnight (Norbert incident) Draco uses "Professor" everytime he speaks 
to McG. Of course, under those circumstances, he would. So it's hard to 
tell if this is Draco's pattern or a Slytherin pattern.

More interesting is the DADA class that Snape subs. No one calls him 
sir except for Hermione and "Professor" isn't always used either. He 
never corrects anyone. Ron finally gets into trouble for rudeness, but 
by then, he is mouthing off. (and with good reason.)
