Final Answer:
Zach knew the time Henrietta was going to the butcher shop because he overheard her phone conversation where she mentioned her plans, and he happened to be nearby.
Step-by-step explanation:
Zach's knowledge of Henrietta's visit to the butcher shop likely stems from an incidental encounter or eavesdropping on her conversation.
This scenario could involve Zach overhearing Henrietta discussing her plans on the phone or with someone else in a public space.
Social cues and unintentional disclosure of information can be sources of such knowledge.
People often share their plans casually in public spaces, assuming privacy or not realizing that others may be listening.
Zach might have been in the vicinity when Henrietta mentioned the specific time of her visit.
Alternatively, if they share a close relationship, Henrietta could have directly informed Zach about her plans.
Understanding the context of their relationship and the environment in which the information was shared is crucial in determining how Zach came to know about Henrietta's schedule.
It highlights the delicate balance between privacy and unintentional disclosure in interpersonal interactions, emphasizing the importance of discretion in conversations, especially in public spaces.
