Jawon is a training and development manager who has been asked by a professor to speak to her class about careers in training. However, since he is currently conducting an important staff development program, his schedule is very busy, and he must refuse the request. What would be the BEST way to end his message?

Again, I am very flattered by your request.

I apologize that I am so busy right now. Maybe next semester I can speak to your class.

I'll call you if I have some time in the next month.

My training assistant, David, has extensive experience and would enjoy speaking to your class. Please feel free to call him at $469-8000.$
