I'll talk to you later.
What's the rush?
I have to get off the phone now.
I'm not ready to get off the phone with you.
There are other things I need to take care of.
What is it that you need to do?
Please don't be nosey.
I'm not being nosey, it's just a question.
You don't need to worry about that.
That was mean to say.
I am very sorry, but I must go.
I guess.
