I was once walking down my block on Shabbos. i passed by Charlie the button man who wished me a merry Shabbos. Across the street was a little girl. She was about five years old and was holding her mother's hand. She yelled good Shabbos to Charlie who yelled the same right back. The scene didn't end there though. She went on (leading her mother behind her by the hand) "Hey Charlie, did you ever see the Rebbe" she asked. He answered, "Yes." To this she replied "I want to see the Rebbe!" and to this he smiled and said, "Thats great". They both smiled and parted ways. Her mother didnt say a word, she just looked on with understanding.
