Hmmm...I'm guilty of every variety of correcting people's pronuncations. Even though I'm by no means as much of an expert as, say...well, 99.95% of the experts on the Forum...I always correct how people say things - especially when they try to pronounce the Elvish names for things. Although my friends are just like me, so we can be annoying in pretentious as a unit at least.
But you know another type of annoying Tolkien pseudo-mini-not really-expert I am? The one that randomly pulls out
The Sil references to go into everyday life without explaining them to the other people who haven't read
The Silmarillion. Do any of you find yourself doing that? I try to stop, but when they pop into my head, I just blurt them out. Most of my friends know what I'm talking about, but the others just think I'm weird. I think they already thought that, actually, but I just enhanced it. Then there was the day where I tried to explain what Vala and Maia were in History class when my History teacher began to whine about the movies...I kind of launched into a summarized
Valaquenta.
