Jacob Gordon has been kind enough to let me quote his eloquent tweet here:
The news of Farah’s death to me was hard to take into my mind and very hard to keep there. How could it be that he had gone away? He had always been the first to answer a call. Then after a while I recognized the situation: more than once before now I had sent him ahead to some unknown place, to pitch camp for me there.
