Tina: "Wally, can I get your comments on my article by tomorrow?" Wally: "Sure." Tina: "You say, 'sure,' but we both know it's a lie." "You just want me to go away." "You plan to wait until tomorrow and make an excuse." "Then you'll hope I'll give up." Wally: "Yes, but remember, my comments are always worthless, they would cause you extra work and worsen the result." "So if I give you nothing. Everyone wins." Tina: "In that case, thank you for ignoring my needs." Wally: "It's the least I could do."
