Is it really necessary for the whole family to go to my son’s bar mitzvah dress rehearsal? His 10 yo sister has been invited to a new friend’s house. The friend lives a bit of a distance away so I would need to take her there. Is it really necessary for me and my daughter to be at the dress rehearsal? My daughter doesn’t want to be called up or be involved in the bar mitzvah and apparently I have to read something with my husband, but I don’t feel I need to rehearse it. We’ve already put up with so much for this bar mitzvah, it doesn’t seem fair to drag my daughter to this rehearsal for what seems like no good reason. Why are we needed there?
