Famous quotes containing the words dwarf and/or birches:

    When I lie down to love,
    old dwarf heart shakes her head.
    Like an imbecile she was born old.
    Anne Sexton (1928–1974)

    When I see birches bend to left and right
    Across the lines of straighter darker trees,
    I like to think some boy’s been swinging them.
    Robert Frost (1874–1963)
