Famous quotes containing the word friend:
“My consciousness-raising group is still going on. Every Monday night it meets, somewhere in Greenwich Village, and it drinks a lot of red wine and eats a lot of cheese. A friend of mine who is in it tells me that at the last meeting, each of the women took her turn to explain, in considerable detail, what she was planning to stuff her Thanksgiving turkey with. I no longer go to the group.”
—Nora Ephron (b. 1941)
