I've enjoyed conversing with you.
Is there a reason why you're trying to get off the phone so fast?
I've got to go.
I wasn't done talking to you.
I have to do some things, and besides, it's not polite to be nosey.
I'm not being nosey. I'm just asking.
I really don't think it's any of your business.
That's not nice.
I apologize, but I'm getting off the phone now.
Okay.
