Famous quotes containing the words main and/or shock:
“The Temptress has now been shown here—terrible. The story, Garbo, everything is extremely bad. It is no exaggeration to say that I was dreadful. I was tired, I couldn’t sleep and everything went wrong. But the main reason is, I suppose, that I’m no actress.”
—Greta Garbo (1905–1990)
“It is not only their own need to mother that takes some women by surprise; there is also the shock of discovering the complexity of alternative child-care arrangements that have been made to sound so simple. Those for whom the intended solution is equal parenting have found that some parents are more equal than others.”
—Elaine Heffner (20th century)
