One Halloween Night In Monsey
Excerpt from page 243 of Reb Yaakov:
Someone was visiting Reb Yaakov, shortly after he moved to Monsey, when someone Halloween trick-or-treating rang the bell. (Monsey was not yet the largely Jewish town that it is today.) The man assumed that Reb Yaakov would not be familiar with such a non-Jewish custom from his years living in Williamsburg and hastened to explain to him what the children wanted. But Reb Yaakov was not only familiar with Halloween, the Rebbetzin had already prepared bags of sweets for any child that might ring.
