multitasking

I think I just confused somebody because I answered the phone while trying to hold the concentration that I had on the project that I had open. Then they said their name and where they were from, which didn't really register. And then I said, "Hey, how's it going" in a very upbeat voice (like I knew them maybe). Which I think confused them because it was someone from the accounting departement of government agency. I think we may have swaped voice mails a couple times but this is not a person I probably ever talked to on the phone before. 

In any event I came off as very friendly, so that can't be bad right?
