Contest entry for the Daily Flash. Prompt was to use the phrase in the title.
“I’m late for that talk thing I agreed to give. What am I talking about, again?”
“I don’t know what you’re talking about,” said Cheryl, the assistant, desperately trying to prevent the pile of papers from slipping off onto the floor, taking her morning’s work with it.
“You must know! I was talking about it all last week, but then it slipped my mind until just now. I just need the topic – I’m sure the details will come back to me.”
“I don’t know what you’re talking about,” said Cheryl firmly, “because you’ve never told me. You talk about giving your talks, but not what they’re about.”
“I must have said something. Please, think!”
“Alright. I don’t know what you’re talking about, but I’m guessing it’s something to do with last year’s experiments.”
“Experiments? What experiments? I don’t know what you’re talking about! No! This is for the thing with the school party!”
“School party? Now I don’t know what you’re talking about! I thought it was the symposium for the Koreans today?”
“Koreans? I’m not aware of any Koreans! I don’t know what you’re talking about!”
Cheryl sighed. “Just a minute, then. Let me check.” She carefully squared away the pile of papers so that they weren’t covering her keyboard or about to fall off the desk, then popped open the departmental calendar on the screen.
“Right,” she said, “I don’t know what you’re talking about, but I know who you’re talking to. It’s not the Koreans – that's tomorrow – and it’s not the school group – they're next week – it’s the faculty chess club.”
“Ah! Yes! Thank you! Google Alpha! You’re a life-saver!”
