My pain tonight comes not from my body, road weary and tired of travel. 
It doesn’t come from the connective tissue illness with which I have long lived.
It comes from saying good bye to David.
From leaving him behind in a far off place to be cared for by others.
My heart knows that he is in a safe place. In honesty, he is doing very well. Not yet consistent enough to come home.
On the other side, there is a sense of joy. Of Gladness. Tomorrow I will be at home with my family. One more night of travel.
