Inspirational story

My inspirational story come from a man and his 24 years old son. One day, they went from their hometown to the california by train, this was the first time for his son to went to someplace by a train.
When the train moved, his son was very noisy and told anything what he saw. She told that " look that dad, the cloud was following us since our departure, why dad why? and look that tree what a great tree" the other people near the man and his son were laughed at him, and asked the man "whats wrong with your son? have you bring him to the psicology doctor? its not worthed for the boy like your son asking all of it." and the man replied "I had to bring him to the hospital and its the result i am very happy and proud of my son even if for the boy like him is not worthed to ask the questions like that" and the other people asked " but why? your son looks like a 20 years old man" and the man told "ya thats true he is a 24 years old boy, he was blind since he was born and my wife leave me because the doctor diagnose an executed me for the bad quality of my sperm. I through my whole life and fight for him , to bring to the hospital, to make him better, 24 years ago my wife left me, and i have to take care of my son. what a depressed life." and the other people just sat quietly and stunned.

so, my points are :
1. dont judge the people if you dont know whats wrong with them.
2. dont give up and keep tryin to fix your problem, even if you didnt work too much but it doesnt mean nothing.
3. whenever if you said " i know that feel " but you never at their position, dont you dare to judge them.
