The dad laughs once more, then gets serious,"I'm sorry, son, I didn't mean to make this so difficult for you. But I honestly don't feel you are in that great of shape. I mentioned that to my grandson. He is following not that far behind us. I told him that making a climb like this takes a heavy toll on a body, and by the time you reach the cliff, you'll probably be an old man yourself. I told him he'd might better throw you off the cliff too ...and save himself a trip later on."
