LB, I wasn't on laptop at cabin yesterday or today till reading your post now. We're home now. Got heavy snow and rain at cabin.
Sad update about your oldest nephew with alcohol dependency. LB, he's been an alcoholic for so many many years it will take a miracle for him to get clean. Miracles do happen though. He needs one. Alcoholism is a disease. His alcohol dependency doesn't make him a bad person. The fact he actually went to rehab says he wants help in my opinion. I'm not a betting person but I bet he promised he'd go to rehab to his father/your brother before he passed away. If so, his 2 day attempt was a promise to his father. He knows you've tried to help him and I believe he does appreciate your attempts. He's powerless with alcohol. Hopefully since he threatened suicide some agency will keep an eye on him. There comes a time, LB, when you have to let go hoping they hit bottom and will seek help. Your father must also be very frustrated and worried about his grandson.
Good you're wanting to continue to help your younger nephew with intellectual issues. Agreed he needs to be removed from his older brothers alcoholic outbursts etc. The younger one needs removed so he can concentrate on bettering himself in life.
God bless both your nephews with both their parents being gone. That being said there's just so much you can do and your father too.
I hope your younger nephew has somewhere else to live.
How's your knee and have you been driving since you got the go ahead?
