you know something, i bet many avoided him during those times, there is not a lot you honestly can say as there is no way to ease their grief or make it any easier for them though we all wish we could, in truth he was probably thankful to see you and just your presence at the time quite possibly helped him more than any words could.
we all wonder how we will react or how it will affect us but one thing i have learned in my time is that people all react differently and i will never ever call anyone who might not react as some think they should, grief is a personal thing i feel and even though some might not outwardly show it they most likely are an emotional wreck inside... i am pretty much 'immune' to it now, lost my dad at 13, couple of good friends in my teens due to motorbike accidents and one from a freak pit accident, one of my sons at 12 weeks old and shortly after that my mother, most recently have all been my partners family and sometimes she must think i just do not care but i just find it so hard to have the same emotions these days.
Good post mate, makes a lot of sense.
I'm at the stage when I have dear friends I've known for fifty years and all 'creaking' ...
... the thought of a string of funerals fills me with dread tbh.
