Nagging is NOT reminding someone about something - that stuff is great. EVEN if you remind someone multiple times this can be a-okay.

No, real nagging is designed to DESTROY your brain. Lets dive in.

1. Nagging is usually something in the PAST (ie. unchangeable) OR something ridiculous.

2. A nagging-subject is quickly forgotten and replaced with a new subject whether completed or not.

3. Nagging often brings up multiple subjects at once - one does not simply get nagged about one thing - overloading your brain and causing stress as resolution becomes impossible.

4. Nagging is often timed for the worst possible moment - such as the second you try to sit and relax after working hard or during dinner.

5. A good nagging request requires the changing of HABIT (such as leaving lights ON when leaving the bathroom, counter to the saving-the-planet/wallet-habit of turning lights off when unused ... no not made up).

6. As in the example above nagging is often counter-productive ie. requesting nonsensical changes adding the potential bonus points of a fight over it.

So analyzing these traits it becomes clear that nagging is a neurological WEAPON designed to stress you and drain your energy.

I can only assume women do this to keep their men controlled and too tired to seek other female attention because otherwise it would not make sense to drain their own husbands.
