My dad thinks he cannot come home in this state because mom won't be able to take care of him. We do need to wait and hear what the doctor says. But yeah, I can see how one is never truly prepared to lose a parent. My dad is 82 years old. He's lived a good life, but without this disease, he could have lived until well in his 90's. His mother smoked in the home, so it's from second hand smoke that he got this lung disease.

Thanks for the hugs.
