Famous quotes containing the words land and/or snails:
“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
—Germaine Greer (b. 1939)
“little snails at the back
of the knee building bon-
fires ...”
—Anne Sexton (1928–1974)
