Step-by-step explanation:
The narrator presents several pieces of evidence to support that the morning was not 'out of the ordinary'. First, the narrator mentions hearing a train running towards Woking, indicating that train travel was a regular occurrence in the morning. Second, the narrator states that instead of working after breakfast, they decided to take a walk towards the common, suggesting that leisurely morning walks were a usual activity. Third, the narrator mentions chatting with their neighbor who was gardening, implying that this was a regular interaction. Finally, the mention of soldiers making people lock up and leave their houses on the outskirts of Horsell suggests that this was a usual response during that time. These pieces of evidence collectively depict a morning that was not unusual or extraordinary.
