Question
If a man has to choose between building his own sukkah and building his father’s, whose sukkah takes precedence?

Question
The Yom Kippur are worded “We have sinned …,” implying that every Jew who recites these prayers is not only praying for the forgiveness of oneself, but for all their fellow Jews. Does not mean that if one fails to pray or lacks kavana as they pray, they are still forgiven because plenty of their fellow Jews have prayed for them to be forgiven? Or must each person recite these prayers oneself in order to be forgiven?
