I believe that standing means different things to different people. I see no reason to be so abrupt with others because their definition doesn't match your's. We want our WA's to show us respect but sometimes we treat our fellow LB's with little respect. What is that all about???
Everything happens for a reason, maybe Dad needs to find that it isn't better out there, he needs to realize how good he had it here. Maybe he will find God and that is the most important thing when he finds Him he will know he is supposed to come home.
