Well, yes and no. Kiel has shared himself throughout much of his life. He has helped others as well as sometimes harming others. There are people who spent parts of their lives with him, who cared about him.
When Gezka first meets Kiel he is not part of a group of close friends and does not have a wife. He is ‘on his own’. How does he really feel about this? It depends on many other conditions; some days he is happy enough, other times not. Kiel is extraordinary in some ways and very ordinary in other respects. He will seek and make friends in any environment where spends more than a day or two.
