"to pull away", not a colloquial phrasal verb?
Well, if you want.
But I beg to differ.
And
I can back up my claim:
http://www.thefreedictionary.com/pull+away
Look at the first example in the list of
phrasal verbs...
Anyway, just try dropping the preposition "away".
" Well, you just
pull it, you peel it off."
Quite obviously, most of the meaning is lost...
And what does this change anyways?
Context is what matters most here: the whole sentence is about
explaining to laymen the process of CD, using
non-technical, descriptive terms which don't appear to have any fixed, precise meaning in CD world. "pull away" and "peel" are obviously descriptive terms designed to help non-experts having a grasp of the whole process.
Why the hell would LS attempt to
describe the process of demolition on that fateful day?
