> But, we're told Snape was even worse to the students after 
that.   And it seems reasonable...he's bent out of shape at being 
laughed  at.  But, what if there was something else going on that 
made him  upset and Harry thought it was the Boggart class? 
Ideas, anyone?

Well, I've been sitting on this, but you've given me too grand an 
opportunity. Snape is upset because everybody is saying what a 
great teacher Lupin is and...wait for it...Lupin can't *do* the 
riddikulus spell -- not successfully any way.

PoA --  ch 7 Lupin turns the silvery orb  into a cockroach. For 
years we've been asking ourselves what's funny about a 
cockroach. The answer is, nothing. It's something else horrid. 
IMO, like Molly, Lupin can't manage the spell.

ch 7 -- Neville uses Riddikulus to burst the boggart in pieces

ch 12 -- Lupin says Riddikulus and the boggart changes into a 
silvery orb. Lupin forces it back into the packing case by 
threatening it with his wand

GoF ch  31Harry uses Riddikulus to explode a boggart in a wisp 
of smoke

OOP ch 9 Lupin says Riddikulus "very firmly and clearly" The 
boggart turns into "a silvery orb" . He then waves his wand  again 
and the orb "vanishes in a puff of smoke."

 Lupin never manages to turn the orb into something funny, 
  and he never uses Riddikulus to make the boggart explode.

somebody caught it
