Overheard at a coffee shop

“You never understand what I’m saying.”
“But I do.”
“No, you don’t.”
“How can you say that?”
“Because you never do understand. I know.”
“How do you know?”
“You never remember what I’ve told you.”
“Okay, but that doesn’t mean I don’t understand you.”
“So, you do understand my feelings?”
“Of course. I think I know you better than you think I know you. Do you know me at all?”
“Of course I know you. I know you better than you know me. I’m good at knowing people.”
“Okay. Let’s order ice-cream.”
“No, too many calories. I’ll have coffee.”
“Okay.”
