Famous quotes containing the words real and/or space:
“The Troubles are a pigmentation in our lives here, a constant irritation that detracts from real life. But life has to do with something else as well, and it’s the other things which are the more permanent and real.”
—Brian Friel (b. 1929)

Wheeling and whispering come,”
