An elderly couple walked into a diner and ordered one burger, a side of fries, and a drink.

The old man unwrapped the burger, carefully cut it in half, and placed one half in front of his wife.

Then, he carefully counted the fries, splitting them into two equal piles. He took a sip of the drink, passed it to his wife, and she took a sip before setting it back between them.

People at nearby tables started whispering. “Oh, how sweet… but also kind of sad. They must be sharing because they can’t afford two meals.”

A kind young man walked over and said, “Excuse me, I’d love to buy you another meal so you both can have your own.”

The old man smiled and shook his head. “No, thank you. We’ve been sharing everything for years.”

But as the meal went on, the young man noticed something strange—the wife hadn’t eaten a single bite.

Concerned, he approached again. “Ma’am, are you sure I can’t get you something to eat?”

She smiled and replied, “Oh, no, dear. We always share everything.”

The young man hesitated. “Then… what are you waiting for?”

She patted his hand and said with a grin, “The teeth!”
