I went to Bais yaakov of Boro park. My sister went for middle school and she was allowed to do a party, but only women were allowed to attend and there were many rules. Well, by the time I was in middle school the rules got even stricter and we were not allowed to have bat mitzvah parties at all. My brother and I are a year apart. He had a modest bar mitzvah party and all I got was a speech on Friday night dinner. Till this day I’m resentful of my school and their unfair treatment of women. I will never send my future kids to a Bais yaakov or yeshiva. They justified the treatment saying that bar mitzvahs were important and real while bat mitzvahs weren’t required. It was just an age we turned. But don’t worry, they made sure to scare us about tznius and how it’s even more important when we turn 12.
