If ever thou shall love,
In the sweet pangs of it remember me,
For such as I am, all true lovers are,
Unstaid and skittish in all motions else,
Save in the constant image of the creature
That is beloved.
– William Shakespeare
Twelfth Night, Act 2, Scene 4. As they wait for Feste to arrive to sing, Orsino tells Cesario (Viola) to remember him whenever he falls in love and he speaks about the nature of his love.
