This is a bit hard to explain, so here's an example:
His room was an exact replica of mine. The only difference were the things he had brought along: his zoology books, his backpack, and of course his climbing equipment. Little objects that told me something about him, but that at the same time, pushed him further away, into a mist of knowledge and practicality.
As you can see, the second list follows the 'sequence' of the first one:
Knowledge = zoology books
Practicality = his backpack, climbing equipment
Do writers follow this rule? Or it doesn't matter?
The reason I ask is because I want to write a mist of practicality and knowledge instead (it sounds better to me for some weird reason).
