"Dr. Luce introduced the concept of "periphescence". The word itself means nothing; Luce made it up to avoid any etymological associations. The state of periphescence, however, is well known. It denotes the first fever of human pair bonding. It causes giddiness, elation, a tickling on the chest wall, the urge to climb a balcony on the rope of the beloved's hair. Periphescence denotes the inital drugged and happy bedtime where you sniff your lover like a scented poppy for hours running. (It lasts, Luce explained, up to two years--tops.)"
