Which quotation best demonstrates how a character’s dialogue conveys a theme about the dangers of isolation?

In the old days, a good part o' the best men here knew a hundred ports of something of the way folks lived in them. Shipping's a terrible loss to this part o' New England from a social point o' view, ma'am."
