Mrs. G., a resident of Boro Park, was sitting with her friends at a chassana. Across the hall she recognized Zelda, who used to live in the community, but had moved away. Although Mrs. G. Was comfortable sitting with her friends, she realized that Ahavas Yisrael required greeting Zelda, who was all alone. Mrs. G. Got up, went over to Zelda, and greeted her warmly. The next day she got a phone call from Zelda’s cousin, who said, “You did such a chashuvah mitzvah last night. You were the only person who spoke to Zelda. She’s just moved back into the neighborhood, and was feeling awkward until you came over.”
