Describe when the men wished each other happy new year. When was it and why?

Eliezer runs to find his father when people start wishing each other a happy new year, but neither he nor his father say anything when they see each other. They both understand that the other is reluctant to observe the Jewish holiday. Eliezer and his father refuse to fast for Yom Kippur, and Eliezer feels a pleasant revolt against God. Nevertheless, he still feels a void in his soul.
