The two sentences in the excerpt that are examples of characterization which suggests that Paul is a superstitious person are:
• He found, as he often told my sister, broken horse-shoes (a "bad sign"), met cross-eyed women, another "bad sign," was pursued apparently by the inimical number thirteen—and all these little straws depressed him horribly.
• One day on coming back home he found one of his hats lying on his bed, accidentally put there by one of the children, and according to my sister, who was present at the time, he was all but petrified by the sight of it. To him it was the death-sign.
