Thanks Sabau - I've talked to my brother about this in the past. To my surprise, he does take mature ownership over his actions and their effect on others. You're right - I probably need to remind him and have faith that he'll adjust accordingly.
I asked my dad this morning, as he was struggling to say something, whether he is having a hard time thinking or speaking. He said he can't find words. It was heartbreaking - how frustrating that must be for him
Thanks for your support
