A woman who won’t stop. She’s like a monster that follows you everywhere and won’t let you be happy until you do what she says.

'I’ve been nagging you since Tuesday. You better do your homework now!'

'I’ve been nagging you for a week. You're not getting any pizza until you clean your room.'

'You didn’t bring me coffee this morning. I’m gonna nag you until you’re dead.'
