It is said that a boy makes other males jealous of his companion, whereas a gentleman makes other females jealous of his companion.

Pithy, but dangerously incorrect. The result of such pandering is tragedy. Perhaps a boy in a man’s body does this latter thing.

The true result of love’s momentum is this: contagion. A gentleman and his companion may be recognized not by the jealousies they inspire, but by the most obvious of diagnostic criteria…

…as if by magic, others fall madly in love in the wake of their arrival or attentions.
