Where does it stop? What if you grow apart? What if time has changed you so much you are no longer recognizable to each other?
It shouldn't matter, says one answer. Loyalty should never stop. And I think there's a grain of truth in that.
But then, if you say it never stops: at what point does it become blind and meaningless?
It doesn't, would be the only logically consistent answer. But that cannot be all there is to it. That would be far too simple.
If someone has changed beyond all recognition, thoughts, beliefs, values, habits, and all, is s/he really still the same person? To insist that s/he is---should that be seen as a necessary kindness rendered to him/her, or a grave disservice, or perhaps an unnecessary and silly mistake?
And, in particular (a bit of a leap, but I started out pondering
these questions and somehow got to those other questions above), how hard should we hold on to those who are about to leave? Yes, they were very kind to us. Yes, we owe a great debt of gratitude to them. Yes, we would all be happier if they weren't leaving. But we are all mortal, after all. And at the end of the long, long day, when it almost seems like they have decided it's time to leave, how hard should we fight that judgement that they make?
Maybe there just are no universal answers. We can only give the benefit of the doubt, and navigate each individual conundrum as (or hopefully before) it comes into sharp, uncomfortable focus.
