Popa – great minds think alike. (And so do we.)
Once we’re discussing this, I would strongly suggest that everyone take a quick look in the Mishna Berurah Siman 27 S”k 33.
He speaks extremely harshly about people who wear their Tefillin anywhere past the place where the hair roots grow. (If you look around shul, you’ll see many people who do this.)
He says that people who do this are “?????? ?? ????? ????????”, and it’s a “???? ????? ??? ??? ?????”. He says that one should warn his friends about this, and then he ends with a quote from the Pri Megadim: “??????? ??????? ??? ?????? ??? ??????? ?????”
