Famous quotes containing the words protected and/or mode:

    “When a girl’s under 21, she’s protected by law. When she’s over 65, she’s protected by nature. Anywhere in between—she’s fair game.”
    —Stanley Shapiro (1925–1990)

    “Yours of the 24th, asking “the best mode of obtaining a thorough knowledge of the law” is received. The mode is very simple, though laborious, and tedious. It is only to get the books, and read, and study them carefully.... Work, work, work, is the main thing.”
    —Abraham Lincoln (1809–1865)
