A: Mr. Johnson, may I have a word with you?
B: Of course, Lucy. What can I do for you?
A: This is difficult for me, because you and I have worked together for so long, but I've found a new position at another company.
B: May I ask you why?
A: You see, I've learned a lot here, and appreciate the opportunities I've been given here, but…
B: Is it something I've done, or haven't done?
A: Mr. Johnson, you've really been great to me, and I'm grateful that you've taken me under your wing and taught me so much.
B: I must admit that I'm still confused. If there's nothing wrong here, why are you leaving?
A: Well, I feel I've grown professionally as much as I can here, and I need some new challenges.
B: I see. Then I do want to wish you all the best in your new career.
A: Thank you very much, Mr. Johnson.
