You were on a plane heading home after your vacation. It was a long flight and it was dark since all the windows were shut and it was late. You wanted to read but didn’t want to wake up others since you needed to turn on your reading light. Just then, your seat mate switched on his overhead light. You quickly opened your book and started reading. For a few hours, light stayed on until you finish your book. Seems like he waited for you to finish your book. You glanced at him, he chuckled.

“How was your book?” he asked.

“It was good.” you replied with a smile.
