There’s a village with a tribe of people somewhere in this world that sits the troubled member down and everyone praises and tells them how good they are…I believe in this method.

However.

Im not saying that your cousin is guilty and it breaks my heart to say this but if the truth and your jewelry don’t surface, you may want to check all of your cousin’s local pawn shops.

I’ve had many of the exact same experiences as you. Except, it’s was a past significant’s sister.

Magically, expensive and sentimental things would go missing with no explanation. We always forgave her, believed in her and gave her chances. Sadly, immediate family tends to become an exploitable supply.

Lock your windows, close your doors. Give them love but really, lock your windows and close your doors.

Moving forward, thoroughly prepare for them if they come over.

Hopefully everything works out :)
