Not exactly the first conversation but happened on the 3rd or 4th day.
Me: Do you know the guy who sits beside me?
Colleague: Hmm. No.
Me: The guy who speaks loudly on phones.
Colleague: Ahh. That guy.
Me : I feel that he is screaming in my ear. Sometimes, I feel like taking a chair and throwing it at him. (Gives a big smile).
Colleague: (A quizzical look).
