When an old man and a young man work together, it can make an ugly sight or a pretty one, depending on who's in charge. If the young man's in charge or won't let the old man take over, the young man's brute strength becomes destructive and inefficient, and the old man's intelligence, out of frustration, grows cruel and inefficient. Sometimes the old man forgets that he is old and tries to compete with the young man's strength, and then it's a sad sight. Or the young man forgets that he is young and argues with the old man about how to do the work, and that's a sad sight, too.
