Sibling rivalry

With an expert flick of the wrist, Faramir loosed his stone. It bobbed over the water like a heron, skimming the surface once – twice – six times before plummeting into the river. 

"Lucky throw!" Boromir thumped his brother's shoulder, ungracious in defeat.

Faramir elbowed back. "The wise man does not believe in luck," he quoted sententiously.

"He who wrote that never had a horse killed under him in battle."

"Likely not, considering he was an Umbari eunuch."

Boromir winced. "That would alter one's expectation of fortune." He bent to choose another flat pebble from the strand. "Best out of seven instead?"
