Read this passage:
macbeth. seyton! -i am sick at heart,
when i behold - seyton, i say! - this push
will cheer me ever, or disseat me now.
i have lived long enough. my way of life
is fall'n into the sere, the yellow leaf,
and that which should accompany old age,
as honor, love, obedience, troops of friends,
i must not look to have, but in their stead,
curses, not loud but deep, mouth-honor, breath
which the poor heart would fain deny and dare not.
seyton!
- william shakespeare, macbeth, act v, scene ili
