Lets say John and Peter are classmates. Peter eats slowly, and talks a lot while at it. John cannot enjoy the food while talking, so he prefers to finish off all courses and continue conversation after that. John is interested in the conversation.
The location is university's canteen, and they ordered first and second courses. It is quite crowded, but they sit in front of each other at the table.
Peter usually talks about his daily adventures, and sometimes asks semi rhetorical questions. His face expression tells John that he expects an answer, or any other kind of voice feedback. Though Peter uses written communication method for important things, so what Peter says during dinner is just regular conversation.
Peter perceives John as blunt person, but John knows that Peter might get frustrated by direct answer.
The country is Kazakhstan. It is located in Central Asia, to the south from Russia (just in case you don't know where it is, which is usually the case with foreigners).
How can John politely tell Peter to hold on with the conversation before he finishes the food? Will it be better for John to suggest Peter to eat his food too?
