"Three years! In statistics, in biochemistry and in my own experience, the duration of love is identical. A disturbing coincidence. Why three years and not two, or four,or six hundred? To my mind, this research simply confirms the validity of the three stages of love as defined by Stendhal, Roland Barthes and Barbara Cartland: passion-intimacy-boredom, a cycle in which each stage lasts precisely one year- a triad as sacred as the Holly Trinity. In year one, you buy furniture. In year two, you move furniture around. In year three, you argue over who gets the furniture." F. Beigbeder, Love lasts three years; Harper Perennial: London, 2007.
