Sluggy, drunk, told Snape about the chosen one

So here's a scenario.

Snape has gone to the potions room to look for that missing potions 
textbook - it's "on his mind". Anyway, Sluggy isnt' there. He puts 
two and two together and thinks of the venom. He finds, in Hagrid's 
hut, the two sleepers. Sluggy wakes. 

"Severus, the most extraordinary thing. Potter told me he was the 
chosen one. He said he's the one who has to kill the Dark Lord."

"Potter is always full of fanciful stories, Horace. Anyway, I was 
looking for Mr. Potter, but I see he was here and has left. 
Goodnight." Sluggy duly passes out again, and will forget the 
incident.

Remember that Potter's "luck" was running out as he made it to the 
castle.

So now, when Snape sees Albus on the tower, the next time he sees 
him, you will note, he knows this bit has been kept from him. He is 
enraged. He's never been trusted. It was all just crap.
