A blind friend visited a relative's house and it was already dark when he was about to go home after dinner. So the relatives lit a lantern for him and told him that there was a lantern for walking at night.
This blind friend was upset, and knew that I never walked with my eyes and gave me a lantern, didn't he laugh at me.
The relatives quickly explained that they were really sorry and had no intention of laughing. Do you think that you are the only one on the way home, this lantern is not used to illuminate the road, but to be shown to pedestrians on the road. In the dark night, pedestrians will see you when they see the lantern, and when they see you, they will get out of the way, and it will be safe to walk.
The blind friend listened to his relative's words and felt that it made sense, so he carried the lantern and went on the road. All the way was peaceful. But when he was almost home, he was knocked to the ground. He sat on the ground and angrily accused passers-by, can't he see the lamp in my hand? Passers-by hurriedly stepped forward to help him up and said, I'm really sorry, now I just found out that you have a lantern in your hand, but do you know that the light has been turned off.
