How does the reader know that Okonkwo is worried, not only about the future of his family, but also the future of the village?

Ofoedu tells the men a strange story about an old man and wife from the neighboring village of Ire. The old man has just recently been found dead in his bed and when his first wife discovered this, she prayed for him. Hours later, the youngest wife went into the bedroom and found the first wife dead beside her husband. Also, one of the men makes a joke, saying that he’s seen a white man tons of times, his name is Amadi. So the joke is that Amadi isn’t white, he just has leprosy and the euphemism for leprosy is “the white skin.”
