Just to expand on what was my actual point: for an immortal, a lot of things people in the here and now view as unchanging or as good as eternal, are obviously transient to them. Humans love to project their own time and place across spacetime. Legends of the past, and fantasies of the future, have always said much more about the people that wrote them, than about the ones supposedly being written about. You think pink has always been a girl color? To an immortal, the time when pink was a boy color was like last Tuesday. You think the nuclear family is an universal institution that existed since ever? He's been there and knows you're full of it. I'm just picking obvious examples to make the point clear (and because I'd need some extra research).Yeah, but after you've been through a thousand years of Rome, five hundred more of Byzantium, a couple centuries of Spain, another couple of the British, etc. etc. and you're going to roll your eyes when those newfangled Americans start thinking they're so exceptional.
Of course, not all immortals are going to think the same, but actually being able to see transitions that are too slow for normal people might give one a different perspective. Key word being might. Nothing keeps an immortal from having their tastes and mores set during adolescence so they go all bah-humbug at any development younger than 5000 AC. Let's remember that complaining about the new generation is older than writing, and think about how insufferable can a person who has been through a thousand of them be XD
