Usually a very tough and rude Khan alone with his wife just shows his best sides and feelings. Everything that is not available to others. In the evenings, she often discussed strange things, what stupid bow ties Sigmund chooses for suits, jokes about how his friends behaved stupidly or got into a ridiculous situation, news and plans.
Or it was quiet evenings of gentle cooing, quiet hissing and bubbling on the part of the Khan that he could just finally relax and not build himself an eternally dissatisfied brick. And he almost always pretends to be angry.
