From 'Macbeth'

She should have died hereafter;
There would have been a time for such a word.
Tomorrow, and tomorrow, and tomorrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools the way to dusty death.
Out, out, brief candle!
Life's but a walking shadow, a poor player
That struts and frets his hour upon the stage,
And then is heard no more; it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

[`Macbeth' Act 5. One of Gigi's favourite pieces, which she often used to quote by heart in full]
