Well I mean, seeing where she came from. Everypony adored her older sister, because she provided the sun. But they could not show appreciation to her night, withought night the land would overheat, ponies would not be able to sleep. Yes she only noticed ponies sleeping in her beautiful night but there is no canon proof that these ponies tried to show appreciation for Luna's night. I for one love the night the cold it brings the tranquility, and the smells. But I do not obsession with her. She is also a lot cuter.
