I'm writing a short story. And I realized the opening is filled with question marks:
Ming was disturbed by the faint sound of a piano. He put down his guitar tuner and glanced at the clock. 12:01. Isn't a little late for practicing? Curious, he pressed his ear against the wall. The song was coming from the apartment next door. It seemed to be classical music. Probably Mozart or Beethoven. But weird, Ming thought, no one is living in there. And there was a good reason for it: the ceiling in that room was constantly leaking. It was so serious that—after many attempts to fix the problem—the landlord finally gave up.
Now, however, it wasn't the sound of water but of a musical instrument.
He put on his jeans, grabbed his key, and exited his apartment.
The hallway was silent, as usual. Moonlight streamed through the window, giving the walls an eerie blue hue. Ming stood before room 312 and eavesdropped again.
To his surprise, he could no longer hear anything. Had he imagined the whole thing? He thought of knocking on the door. But what would he say if someone came out? Oh, I thought the piano was being played by a ghost. Sorry for the disturbance.
Ming realized the absurdity of the situation. What was wrong with him tonight?
Is this a bad practice? If so, how to fix it?
(I thought of starting the sentences with "he wondered" instead: He wondered if he had imagined the whole thing
But this adds three extra words.)
