It’s not brain surgery

“A piggy bank? Are you sure that’s what this is?”
“Duh. There’s the slot for the coins, right there in the parietal lobe. And if you flip it over...” Nat turned it upside down to reveal the black plastic plug on the bottom. Next to the Made in China sticker.
“Are you trying to tell me something? That I’m not smart with my money? Because I told you I will pay you back.”
“It’s supposed to be a present.”
“I just don’t think it’s very nice of you, to keep bringing it up like this. I told you I can pay you back on payday.”
“Lucy, I know. God. This is not a big deal, okay? It’s a gift. A joke gift.”
Lucy took the china bank and ran her fingers over its lobes. “It’s not really fair to give me a present when you know I can’t reciprocate.”
Nat threw up his hands and started backing out of the break room.
“I have an endonasal endoscopy in twenty minutes. I’ll see you later.”
On his way to the operating room, he handed two theatre tickets to Marie at the nurses’ station. He bet Wilder Penfield never had problems like this.
