Famous quotes containing the words operating, system and/or support:
“I love meetings with suits. I live for meetings with suits. I love them because I know they had a really boring week and I walk in there with my orange velvet leggings and drop popcorn in my cleavage and then fish it out and eat it. I like that. I know I’m entertaining them and I know that they know. Obviously, the best meetings are with suits that are intelligent, because then things are operating on a whole other level.”
—Madonna [Madonna Louise Ciccione] (b. 1959)
“The twentieth-century artist who uses symbols is alienated because the system of symbols is a private one. After you have dealt with the symbols you are still private, you are still lonely, because you are not sure anyone will understand it except yourself. The ransom of privacy is that you are alone.”
—Louise Bourgeois (b. 1911)
“A father ... knows exactly what those boys at the mall have in their depraved little minds because he once owned such a depraved little mind himself. In fact, if he thinks enough about the plans that he used to have for young girls, the father not only will support his wife in keeping their daughter home but he might even run over to the mall and have a few of those boys arrested.”
—Bill Cosby (20th century)
