Chabadshlucha,
“I remember the time in high school when we heard how that day’s story in Yeshiva was that a visiting Rebbe had asked a Lubavitcher bochur a question. The bochur reverently listened, and then registered shock, before he recovered and answered.
The teacher was curious what had transpired, so he asked the bochur what had happened. The bochur said the Rebbe had asked him what the good tourist sights were. He hadn’t expected such a question from a Rebbe.”
You forgot the end of the story. As the rebbe left, his attendant asked him, “why did you ask that bochur about tourist sites when you’re planning to spend the day in the beis medrash?” The rebbe replied, “nu, it’s a mitzva to love every Jew, so I talked to him about his own interests!”
