Final answer:
The provided text does not contain information about Tim's conversation with his father while preparing for church, so the question cannot be answered with the given resources.
Step-by-step explanation:
The student's question relates to the difficulty of Tim's conversation with his father as they prepare for church. Based on the provided excerpts, none match the exact situation described in the question. The closest scenario involves a character named Peter and his father discussing the locking up of the nursery and the implication of potentially shutting down their automated house. During this conversation, the father proposes turning off their automated systems to live a regular family life, which includes Peter doing basic tasks by himself, such as tying his shoes. This indicates a broader family and technology theme but does not directly answer the question about Tim going to church. Therefore, the correct answer cannot be determined from the provided texts.
