Two sons work for their father on the family's farm. The younger brother had for some years been given more responsibility and reward, and one day the older brother asks his father to explain why.
The father says, "First, go to the Kelly's farm and see if they have any geese for sale - we need to add to our stock."
The brother soon returns with the answer, "Yes they have five geese they can sell to us."
That father then says, "Good, please ask them the price."
The son returns with the answer, "The geese are £10 each."
The father says, "Good, now ask if they can deliver the geese tomorrow."
And duly the sone returns with the answer, "Yes, they can deliver the geese them tomorrow."
The father asks the older brother to wait and listen, and then calls to the younger brother in a nearby field, "Go to the Davidson's Farm and see if they have any geese for sale - we need to add to our stock."
The younger brother soon returns with the answer, "Yes, they have five geese for £10 each, or ten geese for £8 each; and they can deliver them tomorrow - I asked them to deliver the five unless they heard otherwise from us in the next hour. And I agreed that if we want the extra five geese we could buy them at £6 each."
The father turned to the older son, who nodded his head in appreciation - he now realized why his brother was given more responsibility and reward.
