Observe me, and keep me holy

The Gypsy girl carved love letters into trees, filling the forest with notes for him. Do not forsake me, she removed from the bark of a tree in whose shade they had once fallen asleep. Honor me, she carved into the trunk of a petrified oak. She was composing a new list of commandments, commandments they could share, that would govern a life together, not apart. Do not have any loves before me in your heart. Do not take my name in vain. Do not kill me. Observe me, and keep me holy.

Jonathan Safran Foer, Everything is Illuminated
