There is no eternity in any sublunary thing, and least of all in love.
I will love you eternally: My flame will be eternal. Ridiculous phrases! which signify, “My passion will last as long as it will last.”
Note, that in the Love-kalendar, as moments are sometimes years, and years ages, it happens too, that ages become years, and years moments: thus, It is an eternity since I saw you, sometimes means, “I have not seen you these two days:” and “My love will be eternal,” often signifies, “It will last two days.”
Hyperboles are the familiar language of lovers, who are always in extremes; and too often “in extremes by change more fierce.”
