Famous quotes containing the word reasons:
“... to a poet, the human community is like the community of birds to a bird, singing to each other. Love is one of the reasons we are singing to one another, love of language itself, love of sound, love of singing itself, and love of the other birds.”
—Sharon Olds (b. 1942)
“... But if you shrink from being scared,
What would you say to war if it should come?
Thats what for reasons I should like to know
If you can comfort me by any answer.
Oh, but wars not for children its for men.”
—Robert Frost (18741963)
“Its an old trick now, God knows, but it works every time. At the very moment women start to expand their place in the world, scientific studies deliver compelling reasons for them to stay home.”
