The unfriendliness of Elves

I disagree with those who say that Elves were unfriendly. You confuse aloofness with nobility and wisdom. To Elves men were as ignorant, superstitious children, lacking knowledge of the world, its workings and history. The exception would be human lords or members of the great houses, particularly those who were fostered among elves or raised with their traditions like Hurin, Huor, Tuor, Beren, Turin, Aragorn and some Numenoreans of the Second Age. Elves would not wish to associate with the common folk.

Also, association with men may have been a source of grief and anguish to Elves. A living reminder of the transitory and fleeting nature of what had become the mortal lands. I don't blame elves for maintaining their distance from men.
