Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. In the Artscroll "Pirkei Avos Treasury" they bring a story on the mishnah "All Israel has a share in Olam Haba." Someone asked the Chofetz Chaim if all Jews have a share in Olam Haba, why should they do Torah and mitzvos, since anyway they are guaranteed a share in Olam Haba. The Chofetz Chaim answered that it is analogous to a factory owner paying everyone, regardless of what they actually produced in the factory. But the one who did no work will have to sheepishly answer, when asked what he did in the factory, "I took a check." Is this story mentioned anywhere in the Chofetz Chaim's seforim or letters? And if so, which one? I know it is found in Moshe Yoshor's Hebrew biography of the Chofetz Chaim, but I would like to know if it is found in any of the Chofetz Chaim's seforim or letters that he wrote. Thanks a lot.

Question
Is Judaism able to identify the descendants of King David in the modern world? If 'yes,' who are they? If 'no,' when did the line end? Thank you.

Question
King Shaul tried to sacrifice the livestocks of Amalek. It seems that he wanted to tikun negative energy of Amalek. But it made HaShem angry, and ultimately HaShem took away the kingship from Shaul. Is it impossible to tikun negative energy of Amalek? Is there any specific yetzer hara which is impossible to be tikuned?

Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. If a Gentile wishes you "Happy Halloween," would it be permitted to answer him back "You too"? And would the same answer hold true for Xmas and Thanksgiving? Thanks a lot.
