"What happened?"
Old Wang saw Ma Lu tiptoeing out of the kitchen, so he asked.
Ma Lu lowered his voice, "About the pigeon, I think you were right. I've discovered that the pigeon on the building opposite is surveilling us."
"No, that's just an ordinary pigeon," Old Wang shook his head and said.
"Huh?"
Feeling somewhat awkward, Ma Lu conceded, "Alright then."
Just then, the timer for the oven dinged. Ma Lu went to rinse his mouth, spat out the toothpaste foam, and planned to head back to the kitchen for some bread. But after taking a few steps, something occurred to him, and he stopped, looking puzzled.
"Wait a minute, you've never even looked at that pigeon. How can you be so sure it wasn't surveilling us?"
"Because the one who is surveilling us, I met him last night," Old Wang said, "and, to be precise, he's not a pigeon."

Ma Lu gasped in shock, "So there really is someone keeping watch over us? How...how long has this been going on?"
