Last week Reddit user TheRealNayef asked users to answer this question: "What's the most beautiful paragraph or sentence you've ever read?" The inspiration? The first paragraph of Vladimir Nabokov's Lolita:
I just read the first page of Lolita, and it was just so good that I put it down and appreciated it.
"Lo-lee-ta: the tip of the tongue taking a trip of three steps down the palate to tap, at three, on the teeth. Lo. Lee. Ta. She was Lo, plain Lo, in the morning, standing four feet ten in one sock. She was Lola in slacks. She was Dolly at school. She was Dolores on the dotted line. But in my arms she was always Lolita."
I can't think of anything else that is this beautiful... Maybe the start of Fahrenheit 451.
