Famous quotes containing the word lie:

    “In the middle of the night, as indeed each time that we lay on the shore of a lake, we heard the voice of the loon, loud and distinct, from far over the lake. It is a very wild sound, quite in keeping with the place and the circumstances of the traveler, and very unlike the voice of a bird. I could lie awake for hours listening to it, it is so thrilling.”
    —Henry David Thoreau (1817–1862)
