My dad decided that over the past 20 years of subsidizing my meth addicted sisters existence, paying to bail her out of whatever situation she is in...etc; that she has spent her inheritance. I think he is leaving her a token and leaving everything to me in hopes I will have mercy if she needs money for rehab or something along those lines. As the child who has always been there for my dad, I don't think she deserves anything. That is my feelings.
Feelings aside, large amounts of resources in the hands of an addict is like signing a death warrant.
