Famous quotes containing the words real and/or time:
“You can’t be a Real Country unless you have A BEER and an airline—it helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a BEER.”

“I should like a lover to think of the things that I think about. It is all very well being steady when you have got babies of your own; but that should be after ever so long. I should like to keep my lover as a lover for two years. And all that time he should like to dance with me, and to hear music, and to go about just when I would like to go.”
—Anthony Trollope (1815–1882)
