nag at (one)
To lecture or reprimand one in an annoying, pestering manner, especially about something one considers minor, trivial, or inconsequential. Would you stop nagging me already? I'll do the dishes later! Look, I don't like having to nag you about this, but those reports really need to be filed today.
