Indistinct Memory

I was right in the middle of a conversation with my coworker on Friday afternoon when my phone rang. I asked my coworker to "hold that thought" for a second while I grabbed the phone.

I remember my side of the conversation. It went something like this: "This is Kim. (pause) Hi! (pause) Yes, that's fine. (pause) Sure, I can do that. (pause) Sure. You're welcome. (pause) Okay. Bye."

I just can't remember the other side of that conversation. And I can't for the life of me remember just what I agreed to do. It's been bugging me all weekend.
