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)

    If a man, notoriously and designedly, insults and affronts you, knock him down; but if he only injures you, your best revenge is to be extremely civil to him in your outward behaviour, though at the same time you counterwork him, and return him the compliment, perhaps with interest.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    She’s in the house.
    She’s at turn after turn.
    She’s behind me.
    She’s in front of me.
    She’s in my bed.
    She’s on path after path,
    and I’m weak from want of her.
    O heart,
    there is no reality for me
    other than she she
    she she she she
    in the whole of the reeling world.
    And philosophers talk about Oneness.
    Amaru (c. seventh century A.D.)
