[byquist]

Two opposing warriors that, on a better day, might have been buddies:

HOTSPUR is wounded, and falls]

HOTSPUR: O, Harry, thou hast robb'd me of my youth!
I better brook the loss of brittle life
Than those proud titles thou hast won of me;
They wound my thoughts worse than sword my flesh:
But thought's the slave of life, and life time's fool;
And time, that takes survey of all the world,
Must have a stop. O, I could prophesy,
But that the earthy and cold hand of death
Lies on my tongue: no, Percy, thou art dust
And food for--

[Dies]

PRINCE HENRY: For worms, brave Percy: fare thee well, great heart!
