Final answer:
The texts provided do not specify what Peter and his mother eat and drink during their late night talks. Other meals are mentioned in different scenarios, but they do not pertain to the specific interaction between Peter and his mother.
Step-by-step explanation:
According to the texts provided, there is no clear instance where it specifies what Peter and his mother eat and drink during their late night talks. The excerpts mention various meals and foods consumed by different characters in different scenarios, but none directly correlate to a late-night discussion between Peter and his mother.
It might be that this detail is found in another part of the narrative that has not been included in the excerpts provided. From a general perspective, the types of foods mentioned in the given texts range from bread with milk and pie, strawberry ice-cream and hot dogs, to warm dishes of food produced by machines.
However, without the specific context of Peter and his mother's late-night talks, it is not possible to accurately describe their meal.
