Why didn't mr.rosen ask what was in the package that peter gave him to take to uncle Hendrix?

Mr. Rosen likely didn't ask about the contents of the package because he understood the importance of secrecy and trust in their situation. By not inquiring further, he aimed to protect Peter and himself from potential risks associated with the package. Additionally, it reflects a sense of urgency and the need to act quickly in a perilous time.
