The context of the following conversation is sydney got a new batch of prisoners to cook food, and she put the rest to work.:
Sydney says There are so many prisoners who are going to work with me to make food.
The friend responds You're right.  Do you know who doesn't need to work and who does?.
Sydney responds I don't know.  There are people in the prison who haven't cooked anything yet.  I think I will grab them and put the rest to work.
The friend responds That is such a smart idea.
Sydney responds Yeah, it is.  Thanks for helping me come up with a choice.
The friend responds Of course.
