Hello, I am new to this board but not to the situations that are going on in our world today. May I sugest you try putting the horse before the cart, upon her arrival simply
hug your sister and then look her in the eyes and say,
" it's our turn now " no matter what she's done, as long as your both still alive, theres still time, don't wait till the final
reunion, trust me I've been there, my heart goes out to both of you . . .
