I know it too. Only my aunt did this to me. Pretending to be sympathetic to us when we needed it. She stole several valubles including two emeralds that I got for my birthday and a gold nugget that belonged to my mother.
Ouch.
I don't think there's too much thievery in my family.
However, when my great grandmother died, we were in her will (she had quite a bit of money for us) but somehow my great aunt got away with stealing the entire will. We got nothing.
