Verbal permission is good enough for you! You get your class together and start teaching.
You begin with only twenty-five students, which, lets be real, is more than you expected. At first parents are skeptical but they quickly see results as their girls become super eager to attend shul, say blessings, pray, and talk in Yiddish instead of Polish. But most importantly to both you and parents, their attitudes change as well. They don't only learn information from you, but also respect and humility. And they love coming to school. Your heart explodes with happiness.
Quickly your students go from twenty-five to forty to a hundred! That's a lot of little Jewish girls to fit in a tailor shop. As a special gift you sew each of your students a special white collar to attach to their shirts and dresses. Soon other towns are asking you to help them establish schools for their girls. And by 1919 your efforts get noticed by the local Agudas Yisroel (local political party for ultra-Othodox Jews in Poland) and they offer to help financially support the Bais Yaakov movement.
Oh, so now they want to help? You appreciate that they are finally recognizing your idea but aren’t really interested in getting involved with them
Yikes, your brother was right, your school has become too political. Uncomfortable with all the attention you decide to hand over the whole school to Agudas Yisorel and let them run the network of schools you had built
OMG Yaaaaaaasssss! This is just what you’ve been hoping for! Now you can afford to continue teaching your girls and help other cities establish their own schools. You graciously accept their help.
