Betsy:
However, I *don't* like how Sirius treats Snape in OotP. Sirius
knows that Snape is one of the good guys now. He knows Snape is out
there risking his life. 

Bookworm:
And Snape made cracks about how Sirius was snug and safe at home 
while others were out fighting the bad guys.  Personally, IMHO, they 
are both over-grown bullies who haven't made any effort to get along 
with each other.  I suspect that Sirius didn't intend to kill 
Severus but Severus will only think the worst of Sirius. (I'm 
anxiously waiting for JKR to fulfill her promise to tell us more 
about the Prank.)  

What we know is that Dumbledore told Harry that James had saved 
Severus' life.  We have assumed he referred to the Prank, because 
Severus keeps accusing Sirius of trying to murder him.  Is it 
possible we are being fooled - that this isn't the event Dumbledore 
referred to?  Could there have been another time when James really 
did save Severus' life - from a real threat and not a prank?

Or am I reading too much into Dumbledore's lack of specifics?
