How does Mr. Williams know Mr. Harris?

W: There is a person here by the name of Steven Harris to see Mr. Williams, John. He says he is a school friend from college.(53)Could you do me a favor and see if he is in his office?
M: Mr. Williams stepped out a minute ago, Lisa. He said he was going to talk to Dan about next week’s seminar. Do you want me to go and check for you?(54)I was just about to go and make copies of this report anyway.
W: Yes, could you do that for me? If he is not there, try the second floor conference room. He is scheduled to give a talk to the sales staff about next week’s seminar after lunch today.(55)He might have gone there early to test the equipment he will be using.
M: Okay, I will find him for you.
