Who really said it
Friendship is born at that moment when one person says to another, 'What! You too? I thought I was the only one.'
The thought and the words are Lewis’s, from chapter IV of The Four Loves (1960), the chapter on Friendship. Wikiquote’s sourced section carries two sentences from that chapter. The first: “Friendship arises out of mere companionship when two or more of the companions discover that they have in common some insight or interest or even taste which the others do not share… The typical expression of opening Friendship would be something like, ‘What? You too? I thought I was the only one.’” The second, later in the same chapter, is Lewis recapping himself: “Friendship, I have said, is born at the moment when one man says to another ‘What! You too? I thought that no one but myself…’” The version people quote is the recap’s opening welded to the first sentence’s punchline — which is to say it finishes Lewis’s own trailing ellipsis with Lewis’s own words, and changes “one man” to “one person”. We keep a separate page for the sentence as Lewis wrote it, which is verified.
