Famous quotes containing the word dose:

    Whipping and abuse are like laudanum: you have to double the dose as the sensibilities decline.
    Harriet Beecher Stowe (1811–1896)

    When a mother quarrels with a daughter, she has a double dose of unhappiness—hers from the conflict, and empathy with her daughter’s from the conflict with her. Throughout her life a mother retains this special need to maintain a good relationship with her daughter.
    Terri Apter (20th century)
