i agree, give them nothing. You owe them nothing, but they WILL take everything from you!
You may not thinkit possible, but they do have one goal: To see if you are apostate, and if you ARE? Take you down.
That's it... Take you down. Two witnesses, and hasta la vista.
Already, they have put you in a tight spot, pushed you beyond where you wanted to be. You are explaining things to your dad, perhaps before he was ready... maybe before you were ready? Maybe you couldn't be relaxed, and had to be on the defense?
My mother can only repeat mantras "You haven't been to meetings in two years, you left Jehovah's organization." Even tho bad things have happened to me, she won't listen to me, others have gotten to her first... Those talks at the DC did their jobs... "Do you look for excuses to talk to family members who don't associate?"
I really would follow the advice of so many others and TEXT: "Can't make it today" ...
No explanation (so they can't use your "written text" against you) & can't assign motives. Then, like all the others have said, "just don't reply."
I hope it works out well for you, losing family is very, very hard. (You don't think it will happen, but it does, it has... They "know you are a good person, loving, truthful," right? )
Just text.... then drive.... drive on with your life
:-)
