Poison... or is it?

Just questioning myself about poison... not the kind that kills you... well I guess it could.  I have two sisters... one with my mom, and one with my dad.  They are both night and day.  One is the absolute perfect sister you could seriously ask for.... no matter what it took she would be there at the drop of a hat, she would give me a kidney if I needed one (atleast I think she would), I've always wanted to be just like her... the list goes on.  The other one....plain out hates me.  My whole life I have tried to love her unconditionally.... and admired her for her strength. God made her part of my life for a reason right? We haven't talked in I don't know how long.... and I don't even know if she thinks about me.  The thing that gets me, is I think about her all the time.  She is part of me.  We share a very important part of our lives.... and to think that when we lost that part.... we lost eachother for good.  Our dad was so important to each of us in completely different ways... if only we could share our memories... keep that flame alive.  Sometimes I wonder if I should try again... but then I remember that feeling of poison. That taste of bitterness..... knowing that no matter how much I loved her, she would never love me back.  I know I'm not a bad person... and I'm geniune.  I know I have my moments... we all do.... but one thing you won't find in my heart is hatred.  No matter what.... I forgive always.  Words hurt... but they are just words.  Poison though.... it's not healthy.

Moral of my story is.... Forgive.   No matter if the person wants you too or not.... No matter if you don't even exisist to them.... Forgive for yourself.
