There's a difference in the types of elves you meet

A fun idea to think about when original members of a species stick around through all of their collective cultural evolution

Glorfindel has seen some shit.
- Galadriel also has a pretty impressive list of horrors.
  saw the Two Trees die
  grandfather murdered by one of the gods before murder even was a thing
  witnessed the massacre of her mother's kin
  cursed by the Valar
  walked across the Helcaraxë
  saw the rise and fall of the Noldorin kingdoms of Beleriand
  escaped the sack of Menegroth
  present in the War of Wrath and the following ruin of Beleriand
  rules Eregion with Celeborn until Sauron's attack destroys the realm, escapes to Lothlórien
  daughter captured and tortured by orcs, leaves to the West heavily traumatized
  high royalty born into literal paradise, ends up holding the last pieces of elven civilization in Middle-Earth together and ruling over a forest
- He’s also done some shit.
That's the problem with immortality, hanging around and holding back the culture.
ESPECIALLY when the oldest of them are basically in charge of everything.

Wood Elves, High Elves and fucking Noldor...

What we are really talking about is 3 different cultures, not 3 different writing styles.

The Noldor's slogan is "Kinslaying: fun for the whole family!"
- While that is an act they are surely well known for, the ACTUAL Noldor slogan is 'MINE MINE GIMME MINE FUCK YOU MINE! WE WILL BURN IT ALL DOWN BITCHES!'
  It sounds prettier in elvish.

I'd really prefer to live among the Hobbit elves.. Beginning immediately.

Hobbit elves are just LOTR elves when there aren't any humans around
- There's actually a whole tragic backstory of their king having PTSD and refusing to deal with the darkness growing in his woods because of it, escaping into feasting and singing instead because to act would cost elven lives, but also yes.

That is one of the flaw in the hobbit movie imho, in the book they tease the dwarves and sing silly songs and are generally very lighthearted. In the movie they are almost dour in comparison to the dwarves. But the hobbit was much more of a childrens book that the lord of the rings.

... Those were wood elves, Elrond as a high elf acted markedly different in that exact same book.
- Yeah I guess. But these lighthearted wood elves don't appear in either film series. Maybe in the upcoming reboot (jk)
