I have been asked by various members of my family why I no longer attend meetings. I tried to avoid giving an explanation for as long as I could but there comes a time when you have to face the situation.
We are a very close family so they know me very well anyway. I ended up explaining the process I went through. That made it personal so they could understand my feelings. I explained how I remembered the publications coming out about 1975 when I was 11 years old, how I studied them, got baptized, etc etc, basically told the story of my life so they got emotionally connected. I told how I felt after 1975, through the next 20 years until finally the "generation of 1914" was discarded in 1995 through to the inevitable result of me no longer attending.
My family now feel sorry for me but they don't shun me. If I had said, "I realised it wasn't the truth when the end didn't come in 1975 and then they did a complete turnaround in 1995 and I'm done with being lied to," that may have closed the door on any further communication.
Most JWs who leave don't do so overnight. Everyone goes through a process and has a story to tell. If your sister truly cares about you, she may be willing to hear your story. But she most probably wouldn't be able to cope with hearing about CofC or JWD.
I live too far away to help her when the bomb really hits home and shes on her own
I wouldn't worry too much. Since my initial conversations with my family, we have had more indepth discussions on topics such as 607. But nothing I've said has convinced anyone.
It's probably best to relax, have a good time with your sister, let her see what a normal and loving person you are. If the opportunity arises for a discussion, take it, but if not there's always next time.
