: With his eccentric personality, was Henrik
: even close to members of the other royal
: families? Did he cultivate friendships with
: Constantine, Harald, or Carl Gustaf? Or was
: everything just mere pleasantries and
: cordiality for him during his half-century
: of marriage to Margrethe?
It's difficult to tell how close he was to the people you mention. When it comes to foreign royals and nobles, I think most of his friends came from Germany, Belgium, France and Italy.
If you are suggesting that his 'eccentric personality' made it difficult for him to bond with others, then it's wrong. He had a wide circle of friends who all describe him as loyal and attentive, which goes hand in hand with Henrik's altruistic approach to life.
