Why did not Jonas tell Benjamin how much he admired his work?

Jonas may have refrained from expressing his admiration for Benjamin's work due to feelings of insecurity or fear of vulnerability. He might have worried that sharing his thoughts could lead to envy or complicate their relationship. Additionally, he may have believed that Benjamin already received enough recognition and didn't want to add to the pressure. Ultimately, Jonas's hesitation likely stemmed from a combination of personal apprehensions and a desire to maintain their dynamic.
