"Because I said so... That's why."
"But, Sir... We've been digging this hole for 5 years now. We came here to build a tower. So far, there's no signs of a tower forming," the Boy replied.
"Well, keep digging. I'm sure a tower will sprout from this hole eventually."
"All due respect, Sir - I'm not sure these people even want us digging a hole here. How will we know when we're done digging it?" asked the Boy.
"When the people here fill it back up. That's how we'll know a tower is about to grow."
"No offense, but we're much better at digging holes than they are at filling them. Why should we keep digging this hole?"
"Because it's not hole-y enough," replied the Man with an audible level of irritation in his voice. "See... The people back home? They've just offered to pay your salary to dig this hole for another year, but they've asked that you come home after that year. I say that means they don't believe in your ability to dig this hole. I'm gonna tell 'em 'no go.' If they don't believe in your ability to dig this hole, we don't want their money."
"So, we get to go home?"
"No! That would be admitting we can't dig a hole. We're gonna keep digging this hole until it's done," replied the Man.
"But, how will we know we're done digging the hole?"
"We'll know we're done digging this hole when there's a tower here," the Man said, rolling his eyes.
"Again, sir... I mean no disrespect, but... It seems kind of counter-intuitive to dig a hole when you want a tower."
"A hole is just a tower upside-down," the Man said.
The Boy levels a stare at the Man, who shifts uncomfortably.
"Kid... I like you, so I'm going to level with you. This hole is all I've got. Some things have gone wrong, and I blamed this hole. Some things haven't gone right, and I blamed this hole. I've been willing to sacrifice my friends, lie, cheat, and steal to justify this hole. If you were to fall into this hole, there's a hundred thousand other kids to take your place digging it. I will do whatever it takes to keep digging this hole. I've told the people back home and I'll tell you now, if you're not for digging this hole, you're against our home. So, I suggest you stop asking so many questions and keep digging."
The Boy holds his stare for a moment longer, then wipes the sweat and dust from his brow and grabs more dirt with his shovel...
