E porque eu já tinha sido tão feliz, sentia-me miserável naquele momento...
"All things are either good or bad by comparison. A sufficient analysis will show that pleasure, in all cases, is but the contrast of pain. Positive pleasure is a mere idea. To be happy at any point we must have suffered at the same. Never to suffer would have been never to have been blessed".
(Edgar Allan Poe - Mesmeric Revelation).
