I think it's a story about two mountaineers who have an accident, and one of them dies while mountaineering for some reason in the Atlas Mountains- the living one "lost a thread in the darkest of space", so he accidentally dropped his partner. He then goes home to mourn and take care of the dead one's wife. The "wolves" that came on the radio are search teams confirming that the dead one was found.
It seems that the incident changed him, as he considers himself a boy before it happened, and says he "was" a boy.
