“On open ground, do not try to block the enemy's way. On the ground of intersecting highways, join hands with your allies.”

“Sun Tzu said: The art of war recognises nine varieties of ground: (1) Dispersive ground; (2) facile ground; (3) contentious ground; (4) open ground; (5) ground of intersecting highways; (6) serious ground; (7) difficult ground; (8) hemmed-in ground; (9) desperate ground.”

“You seem to look upon depression as the hand of an enemy trying to crush you…Do you think you could see it instead as the hand of a friend, pressing you down to the ground on which it is safe to stand?”

“When your enemy falls to the ground, help him to get up! Never let a man in that condition stay on the ground! To help the weak, be it enemy, be it rival, is an honour for you!”

“Lovers may never meet again, but the ways of enemies oft do intersect: This proves some corollary about gravity.”

“You were afraid this might be the case. Your dad has blocked the front door with the REFRIGERATOR. Looks like he's taking the grounding seriously this time.”
