The fact that a literal giant of a man like Alexander III was totally terrified of making his itty bitty wife mad is so hilarious to me.
To quote his youngest daughter Olga in a biography of her:
“My father had the strength of a Hercules, but he never showed off when other people were present. He told us that he could bend horseshoes and cutlery quite easily, but did not dare do it because my mother would have been furious. Yet once in the study he bent an iron poker and then straightened it out. I remember how he kept his eyes on the door in case someone were to come in!”
