Hard, yes, Dave K.
But we don't understand all that is really going on.
If one thing has sustained me the last 28 years it's knowing I was there for my dad when he paased on. From the ambulance ride, through the Cheyne-Stokes to his last breath. I can't say how much it's meant to me to know that I "done good".
Brother, my heart is with you. and pray you may be sustained throughout the coming weeks. Whatever may happen, let it be done in a good way, and may you and your dad find peace.
