The Conversationalist, from the series of awkward encounters in the working world part 2

So I've already been assigned a project with a partner, a supervisor, and a looming deadline. I think the supervisor might be a little concerned about it, because he keeps calling my partner to see how we are doing. (note: my supervisor has been out of town for a few days, and the project is due tomorrow) Today when he called, he asked my partner to put me on the phone so he could check on my progress. The conversation began as follows:
Mr. Supervisor: How's it going?
Marla: Oh, I'm pretty good, thanks! How are you?
....and then there was a pause....
Retrospectively, I don't think my supervisor was calling to chat.
