Ha! First, your half sister whom you do not have a good relationship with is trying to manipulate you into doing something you don't want. Second, you have never been close to your Mother (like the last three years), and telling a child they are only around for money===they will answer for that.
Third, your Dad is the one who should have the honor of walking you down the aisle, he raised you//where was Mommy Dearest?. Your half sister is a piece of work! You are too nice, why would you want these people in your life now.
Saying nicely, a wedding is not a place for reunions, peace keeping efforts, etc. You know she will throw a fit when you don't want her Dad to walk you down the aisle because for some asinine reason she is wanting the world to think you are one big happy family and not so totally dysfunctional///which is not your fault . They is No need to say anything about staying close, etc. if this is supposed to happen it will (and on her terms) and she doesn't sound like she is doing any thing to make it happen. Just tell her, thank you, but you prefer to have your own wedding, then leave asap.
I would call her, that way you can end the conversation. Have your day and forget about these nutters who have not been in your life. Why start now?
Wrong, wrong time=too much stress---I mean good grief, you haven't even seen your own Mother in three years. Enjoy your day with the man who loves YOU.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
