A long time ago, there was a book called "The Sea of Loneliness".
There is a sea in the book. The sea is painted and will not move.
There is a person who lives in a book and stares at the fake sea every day.
One day, someone knocked on the cover outside the book: "Hey, are you still there?"
"I'm here. But I can't get out," he said.
People outside said, "I can't come in either."
They talked for a long time across a page.
