Here’s my question:
If the mitzvah of Sukkah is learned from “BaSukkot Teishvu Shiv’at Yamim” (You should “sit” in the Sukkah for seven days) from which the gemara extrapolates, “teishvu, ke’ayn taduru,” (“Sitting” means “living”) then why do I need to eat lunch today in a sukkah?
Let me explain the basis for my question. Halachically, I am supposed to move out of my house, and “live” in the sukkah instead. Anything I would normally do in my house, I should be doing in the sukkah, which is why people sleep in the sukkah as well as eat in it. However, regardless of the structure in which I live right now, and where I slept, my “taduru,” my living today would end up at work. And at work, I would order lunch on seamless and eat it at my desk, regardless of where I live.
So why do I need to do any different because it’s Sukkot?
