I find it peculiar which classics actually made it into my reading stack. Because when i was a child and teen, I seemed to have an almost hipster-like allergy to reading anything someone got for me, or recommended to me, just because it was a classic, or popular. (Still do, but not to the same degree, and I have long since recognized it as an unfortunate knee-jerk reflex to be worked around more than indulged). My husband has a WALL of golden age and classic sf paperbacks that are mostly alien territory to me.
And yet, thankfully, one of the hipster inclinations I seem to have avoided is that I don't think less of other people for reading what I do not and have not. How can you do that? It's tiring.
(I also missed some because classic fantasy had a much better chance of being picked up by me than anything with SF on the cover.)
