The dad persists, "No, I'm serious!"

By the tone of his voice, it's obvious that the son is frustrated, "You know that everyone says it's best not to talk. You know this must be done; you're just attempting to prolong this! What must be done, must be done."

The dad insists, "No, I'm not trying to prolong this ...seriously, you don't look well."

The son's tone reflects increased frustration, "I'm fine ...and we're not going to rest. We're going on! And I'd appreciate it if you'd not make this any more difficult than it already is. I will be very thankful if you'd not talk to me anymore!"

There is a long silence. They are three quarters of the way up the mountain, when the old man begins to laugh. He starts out in low, and his laugh builds in intensity.

The son shouts above his dad's laugh, "What is so funny! The laugh is even worse than your talking! If you must, tell me what is so blamed funny!"

The dad chuckles, "I'm sorry, but I think we should stop; I don't think you are in that good of shape. I don't think you can make it."
