Reply To: Inviting Non-Jewish Co-Workers To A Simcha?

To the poster called Helpful:

I am not aware of any posek who says you should sit shiva for a cousin.

Please provide a source.

2: The MB there does not bring down “this” Taz. Even if it does exist, it is probably talking specificly on Yom Tov (as per the Siman). And if it is not, it argues on the Shulchan Aruch and the MB.

Please point me to somewhere I can read it (I don’t have a SA with TAZ at work).
