"Okay, fine."

"But, that's not what I said." 

"Honey, it's what I heard. Let's just drop it for now."

"Okay, but I meant that I understood what you said."

"I don't want to upset you. I know you're not feeling good."

"Really, I'm actually feeling great. Just the usual stuff, but it's fine, dear."

"Well, I just want us to be clear."

"We are clear. I feel that you're really upset with me."

"No, that's not it at all. I mean, I may get upset because you think I'm upset. I'm not."

"We can talk about it later."

"Okay, fine."
