Morsa

“To ensure that erotic friendship never grew into the aggression of love, he would only meet each of his long-term mistresses only at long intervals. He considered this method flawless and propagated it among his friends: "the important thing is to abide by the rules of threes. Either you see a woman three times in quick succession and then never again, or you maintain relations over the years but make sure that the rendezvous are at least three weeks apart.”
― Milan Kundera, The Unbearable Lightness of Being
