True story:
I used to learn during Chazaras HaShatz. One day, as I was davening, I caught my 14-year old son reading a novel during Chazaras HaShatz. When I told him that it was inappropriate to do so, he responded that since I read, there was no reason that he shouldn’t do so as well.
I tried to justify my actions by stating that at least I was learning and such, but, in the end, I had to concede that he was correct and that my actions were just as wrong as his.
Since then, I follow along in the siddur during Chazaras HaShatz. And my son no longer reads then as well.
