Hi everyone! I'm having trouble telling the difference between two similar phrases. Please help me with it. [context] It is from a novel named Mr. Monk and the dirty cop. And it is a description of a big lecture hall in a university. All the seats in the room had power plugs and tables for laptop computers. I imagined that being a student here was like listening to lectures in the business-class section of a British Airways jet. The only thing missing was someone pushing a cart down the aisles serving beverages and snakes. [question] If I rewrite the underlined sentence like this, "The only missing thing was someone pushing a cart down the aisles serving beverages and snakes." does it make any difference in meaning? What is it? To me, the two phrases, "The only thing missing" and "The only missing thing", mean the same. But I thought there must be some differences in meaning between the two. That's why the author wrote in that way and not the way I rewrote. However, I couldn't figure out why.. Would you like to help me? Thank you for reading my post!
