Jewish Holidays

A few minutes from the full shiur "How to Understand the Seemingly “Out-Dated” Mitzvot".

a yeshiva student made fun of his rabbi. His rabbi gave him permission. is that permissible?

I grew up lighting Chanuka candles inside the house. In my community, the uniform practice is to do so outside. I think that is great, but I miss seeing them inside my house. Is it permitted to light a second chanukia indoors (could it be bal tosif)? If permitted, what is the best way to do it?
