Smileless, I can see how someone being told they are heading for eternal destruction (if those are the words used) or eternal death (again, if those were the words used) could be interpreted as 'you are going to hell' by someone who understood that concept better. It's really just a terminology issue based on what terms are understood in what belief systems. Based on what i have experienced, a JW would feel it was the right thing to warn someone that they are on that path. So yes, OP might feel she was told she was going to hell, but how most of us would interpret that, that scenario could not have happened with a JW. Most churches believe in evangelism and saving people do they not? In any case, that is a side issue. In the situation with the house, it doesn't sound like JGran is being at all unreasonable.
Did your son have a written contact with all benefits outlined JGran? As he's family you might not have felt the need, and maybe that is why you are where you are now with this. The bottom line is that you get to do whatever you want with your properties and assets.
