M: Hi, Nicole. Please, have a seat. You’ve done such a great job at our publishing company over the past few years.(62)And as you know, we are expanding overseas.

M: Of course. Why don’t you take the next couple of weeks to think it over?(64)Here is the description of the assignment. Take a look at what the job entails and let me know if you have any questions.
