With the conversation reaching this point, and the other party being polite, Nanny Sun couldn't very well insist on stating her purpose directly.
If she were to ask to borrow someone now, Young Master Lian might well have a reason to say that her two servants were still needed to attend her at mealtime and refuse to let them go.
So, it was better to sit down and wait until they had finished eating before speaking.
This meal turned out to be a real torment for Nanny Sun. She had never seen anything like it, at least not in Driftfrost Hall.
The master ate at the main table while the two servants ate at a lower table. The food on both tables was the same, looking especially delicious, and clearly not the big pot rice from the Imperial Kitchen.
