Famous quotes containing the word present:
“Giving presents is a talent; to know what a person wants, to know when and how to get it, to give it lovingly and well. Unless a character possesses this talent there is no moment more annihilating to ease than that in which a present is received and given.”
—Pamela Glenconner (1871–1928)
