There once was a young couple who spent most of their time daydreaming. On a particular lazy afternoon, as they lounged about in their bungalow, the husband said aloud, "One day, when I have enough money, I'm going to buy a cow."
"Mmmm, yes," said the wife. "And when you get that cow, I will milk it everyday."
The husband was pleased with this, but frowned. "If you're going to milk our cow," he said, "you're going to need some bigger pots to keep the milk in!"
"You're right!" the wife said, concerned. "I'll need three new pots --one for milk, and one for cream!"
"What about the third pot?"
"Oh," said the wife. "The third pot is for my sister. I'll give some milk to her every day."
The husband was enraged. He leapt to his feet, found a stick, then began to beat his wife with it. "You ungrateful woman," he cried, "I work so hard to buy us a cow, and you go and give a third of our milk to your worthless sister!"
The wife was headstrong, too. She found her own stick, and beat her husband harder. "You ungrateful man!" she shouted. "I toil every day milking our cow. This is how you reward me?!"
A neighbour had been listening to this sorry exchange, and decided to drop by just then. He brought his own stick, and proceeded to beat both the husband and the wife.
"Hey!" the husband protested. "Why are you beating us?"
"That's for my vegetable garden!" the neighbour said.
"But," the wife pointed out, " you don't have a vegetable garden!"
"Not yet," the neighbour replied. "But I've been thinking about growing one. And your sorry cow will surely destroy it!"
