Sincerely

"You don't really mean it, do you?"

"What?"

"What you just said. You don't really mean it."

"Why would you say that?"

"Because I can tell. It's okay. You don't have to lie to me."

"Okay, you're right. I was just saying it to make you feel better. I'm sorry."

"Don't be. It did make me feel better."

"Really?"

"Well, until you admitted you didn't mean it."
