Made for You

A bookstall on the Left Bank, a light drizzle, and a man holding an umbrella over you that you did not ask for. You laugh, he laughs, and somehow you end up walking along the Seine together until midnight. Years later you will still say it began with a borrowed umbrella.

“An unexpected kindness will change your direction.”

A 2N Diamond Fortune

Wear it once for courage; it stays for luck.
