Good choice! You and your brother visit the Rebbe. Your brother sent a note ahead saying "my sister wants to educate the daughters of Israel in Judaism and Torah." When you arrive the Rebbe says two words to you: "Bracha Ve'hatzlacha" (blessing and success) and your heart sings!
Though the Rebbe gave you his verbal permission to open your school he refused to put his blessing in print and also prohibited Belzer Chassidish girls from attending Bais Yaakov, which is kind of a bummer. You have to rely on getting students from families who don't mind sending their girls without the Rebbe's permission, or from other sects of Judaism.
Now, here's the big question: Are you bothered?
Um, maybe a little.
