Friendship is inexplicable, it should not be explained if one doesn’t want to kill it.

The remark treats friendship as something essentially lived rather than theorized: its value lies in the unforced, tacit bonds of affection, loyalty, and shared experience that resist neat rational accounting. To “explain” friendship—by dissecting motives, demanding proofs, or turning intimacy into a set of reasons—risks converting a spontaneous relationship into a transaction or an argument, thereby “killing” what made it vital. The line also hints at a modernist suspicion of over-intellectualization: some human realities (love, faith, friendship) are diminished when subjected to excessive analysis. It advocates protecting the mystery that allows friendship to remain generous, free, and alive.
