“To have some account of my thoughts, manners, acquaintance and actions, when the hour arrives in which time is more nimble than memory, is the reason which induces me to keep a journal: a journal in which I must confess my every thought, must open my whole heart!”
—Frances Burney (17521840)
“Don: Why are they closed? Theyre all closed, every one of them.
Pawnbroker: Sure they are. Its Yom Kippur.
Don: Its what?
Pawnbroker: Its Yom Kippur, a Jewish holiday.
Don: It is? So what about Kellys and Gallaghers?
Pawnbroker: Theyre closed, too. Weve got an agreement. They keep closed on Yom Kippur and we dont open on St. Patricks.”
—Billy Wilder (b. 1906)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Grays Anatomy.”
—J.G. (James Graham)
