I know how negative contractions are used, and that they're all pretty straightforward in informal writing.
Didn't she go to the opera with you?
Weren't you a pastor before, Jacob?
Can't we get in trouble for this?
But I feel like the tones or meanings of these questions change when the contractions aren't used. Like the second one:
Were you not a pastor before, Jacob?
It almost sounds accusatory, in a facetious way. As if to imply Jacob had done something to contradict his prior lifestyle. The third one doesn't even sound correct when being used that way.
Does this tone-shift occur because of how we use the contractions in modern times? And in the instance of the third example, are they all still correct even when they don't seem like it?
