He does come off petty in the stories of his dealings with his aunt, but in his defense, I think she could probably be a difficult character. The Danish Court never had as much money as other courts--such a Russia--and I don't believe MF ever really came to terms with the fact that she didn't have unlimited resources anymore. I mean for roughly 50 years, money and comforts were of no concern for her and while AIII was a simple man, he spoiled his beloved wife. Christian X reflected more of the post-war belt-tightening that many royal courts underwent and was frugal to begin with and preferred simpler things, as did many Scandinavian monarchs (even to this day). Plus, I think it annoyed him that she sat on her jewels and expected her relatives to underwrite all her expenses, such as the pension given by George V and the home given by Christian X. While his mother Queen Louise brought a great fortune with her, she had a good number of children to divide it amongst . MF was pretty unconcerned with "petty" concerns such as money and in one famous story, when CX complained about the electric bills, she had every light in the palace turned on. It seems a basic clash of temperaments, lifestyles, personality, etc...escalated into a real feud.
