Potioncat:
Lupin's imprecision with wording is one of the reasons Snape argued 
against his appointment as DADA professor. It wasn't just his 
association with Black.

Mike, you Flintmaster, I never noticed this apparant contradiction. I 
always thought something along your orange example, except, more that 
they drained the good thoughts to create the dispair; that the 
positive engery of the Patronus would be as repellant to a Dementor 
as a Dementor is to wizards. Or something like that.

Oh, and don't go looking for canon about Snape's objection to Lupin. 
I made it up. <eg>
