At Sunday dinner, the first grandchild asked Granddad for the Wi-Fi password.
“Talk to each other,” he said.
Milo typed TALKTOEACHOTHER. It failed. He tried the same words with spaces, then lower case, then a number at the end. Granddad carried the roast to the table and said the gravy was ready.
His daughter asked for the password. “Talk to each other,” he repeated.
“Dad, we are talking to you.”
“Good start.”
She put her phone down. Her brother arrived late, checked the network name, and asked the same question. When Granddad answered, the whole table groaned. He insisted he wasn’t trying to make a point; that was what he had written on a card near the router.
They found the card. In careful handwriting it said: “Wi-Fi: Ask Granddad. Password: talk to each other.”
Milo tried again. Still no connection. Granddad remembered changing the password after a neighbor’s television began appearing on his network. He had put the new one somewhere safe.
“Where?” asked his daughter.
“In my address book.”
His address book held phone numbers, birthdays, a plumber’s name, and a note saying “new password in kitchen drawer.” They opened the drawer. Inside was a second card: “Wi-Fi password is under the biscuit tin.”
Under the biscuit tin was a folded paper with a long string of letters and numbers. The family cheered. Milo typed it carefully. The phone connected to a device called “Printer Upstairs.”
“That’s the printer password,” Granddad said. “Useful if anyone wants to print something.”
Nobody did. The roast was getting cold. Granddad suggested they eat first and deal with the router afterward. During dinner his daughter told a story about the wrong cake delivered to her office. His son described a neighbor who had bought a lawn mower for a garden the size of a rug. Milo admitted he had tried to charge his phone with the television remote’s cable.
Granddad described the telephone two houses had shared when he was young. Whenever his brother wanted a private conversation, the neighbor would clear her throat on the line until he apologized and hung up. Milo could hardly believe anyone had lived that way. Granddad pointed out that Milo had spent an hour investigating a password without asking his aunt how school had gone. Milo asked her then, and she told him a story his phone had never heard.
They laughed. For twenty minutes nobody looked at a screen. Granddad looked pleased, which made them suspect the whole treasure hunt had been planned.
After dessert, Milo went upstairs and found the router. The current password was printed on a sticker underneath. It was the factory password, unchanged. He entered it, connected, and came back down holding the router.
“Granddad, you never changed it.”
“Of course I did. I wrote new cards.”
“You changed the instructions. The password stayed the same.”
Granddad looked at the card trail spread across the table. He had made four notes, misplaced three, and accidentally sent everyone searching for a secret that was printed on the machine.
“So can we put the password on the fridge?” asked Milo.
Granddad nodded. “Yes. Write it big enough for everyone.”
Milo wrote the string on a card. Underneath he added, “Granddad’s preferred connection: dinner.”
Granddad read it and smiled. The next Sunday Milo brought a friend who asked for the Wi-Fi. Granddad pointed to the fridge. The friend read both lines and sat down to eat.
“Does the dinner one have a password?” he asked.
“Yes,” Granddad said. “Please.”
