the loss is different..
the loss of jws is a knife to the gut because they cut us out of their lives.. we are not welcome in their doors..
Morty for example on JWD.. we've lost touch.. but I know without a doubt if I were to find her and show up at her door.. not only would I be ushered in.. but I'd probably not be allowed to leave for a long while..
its like saying good bye for now, (even if it could be forever) and saying good bye and having being slammed in our face..
both may be sad.. but one is on purpose..
the other is by accident..
so one causes sadness at missing..
the other may have sadness.. but it also may include anger, bitterness... disloyalty to friendship..
