I apologise for being harsh on Uncle Billy
I saw this movie a few days ago and only saw one side of George's dilemma, but now it's on TV again at this moment I'm seeing fully how it devastated Billy, and I just didn't get that. I should understand, as I've been forgetful myself, and I noticed Billy's line "I can't think any more, it hurts", meaning that it was, as others said, a mental condition brought on by advanced middle age. I feel tempted to delete my other thread, now, but maybe I'll just edit it to not sound so bad towards him.
Why are you here if you haven't seen the movie yet?
