My condolences for your loss.
You are a better person than me:
My grandmother spiraled down into Alzheimer's over a decade. When her needs were more than the family could provide, we moved her into a living facility. I was the last of the grandchildren to visit her regularly, but stopped when she no longer recognized me and was frightened by "that strange man". I still feel like I didn't 'do enough' to stay with her and stand by her.
So to summarize the situation, there were two options:
A.) Dad tells his son that he can't stand playing 4E anymore because it's crushing his soul and walks away from the game, leaving his son without anyone to play with.
or
B.) Dad tells his son that he can't stand playing 4E anymore because it's crushing his soul and walks away from the game, but Dad buys son hundreds of dollars of books from a new system and says "But I think you'd have a lot of fun with us if you just try this out."
This thread is about a Dad who chose option B. There was some grandstanding in there for dramatic effect, but I don't really think it changed the situation much.
If that's how it happened, without the kid coming home to find all his 4e books gone, I don't think anyone in this thread would've had a problem with it. The OP paints a situation where he never even spoke to his son, just took stuff away and replaced it with an alternative.
I agree, the OP is misleading, because it had actually been an ongoing discussion with people actively leaving the son's game because they were so dissatisfied. Also, the word "took" is misleading. He just moved the 4e books. They are still the son's and he has full access to them.
Big sympathy-filled hug. (Is there an emoticon for that?)... I wish there was more I could have done ...
