What probably really happened:
A blind man was walking with his new service dog. Suddenly, the dog started to be pulling towards a certain direction and the blind man, out of curiosity, followed his dog. A few street corners further, they arrived at a Kingdom Hall. While there were no meetings in progress, two brothers were about to leave and walked towards their car and paused. Who was that blind man arriving here with his service dog? Getting closer, they could not believe it, it was Buddy! The dog of their recently deceased friend! The dog recognized them as well and it was unbelievable! Like finding an old friend that was lost! They had a pleasant conversation with the new owner, trying to understand what had just happened. Before leaving, the man took some literature in braille and went on his way.
Then, through the telephone game, the story became what was posted at the top of this thread.
