What does it mean when someone is living a quiet life?

It means they chose simplicity and have no need for a rollercoaster life of activities or a booked social schedule. They enjoy just being.

Simple with no drama

They are happy with that lifestyle. They don’t need to validate their existence by keeping up with the Joneses or flaunting what they have. They know what they want in life.

maybe it means there is nothing interesting to say about that person's life, its uneventful.

It means I envy them.

That's what I usually have as long as the narcissist stays away and I think he's going to because no one's believing him anymore.

It means they claim they are leaving SW... only to return within the hour.

They have the volume set at 1

they keeping a low profile maybe.

They mind their own business

Simple as that.

Shhhh!
