"Where did you come out?"  Ron asked.
"Knockturn Alley," said Hagrid grimly.
"Excellent" said Fred and George together.
"We've never been allowed in."  said Ron enviously.
"I should ruddy well think not," growled Hagrid.

I read this paragraph over and over and it hit me as kind of 
strange.  I'm thinking about the "we've never been allowed in" part.  
Yes, it could be Mrs. Weasley not allowing them to go there, but the 
way it is phrased sounds more like the grate isn't allowing them in.  
It wouldn't suprise me if Fred and George have tried to get in.  If 
it is the grate that doesn't allow them in (maybe because they are 
young, underage wizards) then why would it allow Harry in?  I may be 
over analyzing this but it just seemed strange to me.  It seems as if 
it was Mrs. Weasley not allowing them in they would of said something 
like, "Mum won't allow us to go."  Am I just crazy?  What do you guys 
think?    Thanks,  Diana
