Famous quotes containing the words variable, envelope, return and/or path:

    There is not so variable a thing in nature as a lady’s head-dress.
    Joseph Addison (1672–1719)

    ... all my letters are read. I like that. I usually put something in there that I would like the staff to see. If some of the staff are lazy and choose not to read the mail, I usually write on the envelope “Legal Mail.” This way it will surely be read. It’s important that we educate everybody as we go along.
    Jean Gump, U.S. pacifist. As quoted in The Great Divide, book 2, section 10, by Studs Terkel (1988)

    Real kindness seeks no return;
    What return can the world make to rain clouds?
    Tiruvalluvar (c. 5th century A.D.)

    After decades of unappreciated drudgery, American women just don’t do housework any more—that is, beyond the minimum that is required in order to clear a path from the bedroom to the front door so they can get off to work in the mourning.
    Barbara Ehrenreich (20th century)
