Good luck man. I hate family that does that kind of ****. had it happen more than once in my family. like i said, keep your head up dave, you know you guys are doing whats right for your father. selfishness makes idiots believe they know what is best and right. truth is, they know nothing, and generally need to stay the hell back and leave the decision making alone.
I've never met you in person dave, but i am sorry you have to deal with this in this way. what should be a time of reconciliation and saying amens to your father has turned into a time of tiring bickering and anger over nonsensical issues. family that will kick a person in a time like this is family that isn't needed anymore. cut those loses, they pale in comparison to your true loss at hand. i hope your father goes quick and peaceful if he does go, and i mean that in the kindest way possible dave. no one should have to suffer once they have made peace with meeting their maker.
