This passage?
"He isn't well, please believe me. Why else would Gregor have missed a train! The lad only ever thinks about the business. It nearly makes me cross the way he never goes out in the evenings; he's been in town for a week now but stayed home every evening. He sits with us in the kitchen and just reads the paper or studies train timetables. His idea of relaxation is working with his fretsaw.

Anyway, I'm glad you're here; we wouldn't have been able to get Gregor to open the door by ourselves; he's so stubborn; and I'm sure he isn't well, he said this morning that he is, but he isn't."
