Which two sentences in this excerpt from Theodore Dreiser's "My Brother Paul" are examples of characterization that suggest Paul is a superstitious person?

Of all those who had been so lavish in their greetings and companionship earlier in his life, scarcely one, so far as I could make out, found him in that retired world to which he was forced. One or two pegged-out actors sought him and borrowed a little of the little that he had; a few others came when he had nothing at all. His partners, quarreling among themselves and feeling that they had done him an injustice, remained religiously away. 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. Finally, being no longer strong enough to be about, he took to his bed and remained there days at a time, feeling well while in bed but weak when up. For a little while he would go "downtown" to see this, that and the other person, but would soon return. 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. Some one had told him so not long before!!!
