George Eliot said this quote

Young love-making--that gossamer web! Even the points it clings to--the things whence its subtle interlacing are swung--are scarcely perceptible; momentary touches of finger-tips, meetings of rays from blue and dark orbs, unfinished phrases, lightest changes of cheek and lip, faintest tremors. The web itself is made of spontaneous beliefs and indefinable joys, yearnings of one life to another, visions of completeness, indefinite trust.
