What I'm trying to understand is when should the logical subject of a negated reflexive verb be put in the genitive case. Problem is, I have yet to find other examples of this with other verbs.
With покупаться and other examples, negation of the verb means the action described does not take place but the subject still "exist" somewhere, whereas with предвидеться the negation implies that indeed there won't be precipitations: осадков не будет. Am I right?
