His Mother read the note out loud to her son
Tears began to fill up her eyes.
"Your son is a genius, none of our teachers can teach him"
"Please teach him yourself" - she read aloud.
Many many years later, after the death of his Mother
The son was looking through his family's records and stumbled upon the letter
He read the letter, it said:
"Your son is mentally deficient and we no longer can teach him at school with other students"
That son's name was Thomas Edison
By that time he had been a famous inventor. Responsible for a number of world changing inventions.
Thomas was a mentally challenged child.
Thanks to positive support from his mother, he went on to change the world.
