<p>correction to Chedva–tefillin are not worn on Shabbat or holidays, only at the regular daily service. Nymom must have attended a bar mitzvah on a weekday. (Perhaps a Sunday, or Monday legal holiday? Torah is also read on Thursdays. Monday & Thursday were traditionally market days when the most people would gather together in town.)</p>
<p>Thanks, mommusic! I didn’t know that! (I did know about reading the Torah on Mondays and Thursdays; my h’s aufruf was on a Thursday morning.)</p>
