What is the difference between using the imperfective vs the perfective? My textbook (a very good compressive one) only mentions future negation in passing.
Я ей не буду говорить об этом.
Я ей не скажу об этом.
Я не буду брать карандаши из ящика.
Я не возьму карандаши из ящика.
As I get it, negated perfective means (won't be able to do it, finish the action, it's not possible (because it really isn't or I just think so)).
But to me it also seems like it means a type of refusal. I won't do it (Am not going to do) vs negated imperfective (I won't do it at all, it's a none issue).
Change the sentences if you wish; just random 1 sec examples.
