What a great story you have shared with us, it happens quite often that when someone in a couple dies their sad companion also ends up dying, on one hand I say sad because they have more people around them that love them, appreciate them and would love to enjoy more time with them but on the other hand losing a life partner can totally destroy you and the only thing you end up longing for is to be with that person in one way or another.
What a nice memory this picture is, I hope it could have been a little caress to the soul.
