Students at Plano Senior High School were surprised at their graduation ceremony last week when Sef Scott took the stage to give the commencement speech. Sef suffers from autism and social communication disorder, so he has rarely spoken during his years of high school.

Sef immediately stunned the crowd by giving a powerful viral speech about “doing the unexpected.” He explained that he was inspired to give the speech by his brother, who is a brain tumor survivor and public speaker for charities. Sef had spent weeks working with his brother and other family members on perfecting his speech, and it’s safe to say that his efforts paid off!

In his speech, he encouraged his fellow graduates to follow his example and do the unexpected in life. Sef said that this could mean doing something small, like giving a gift to a stranger, or something huge that will change the entire course of your life.

“Unexpected is what I want you to remember… while I have a vocabulary like you do and the ability to physically produce spoken words, it is not a normal thing for me to electively speak,” he started his speech.

“Don’t follow someone else’s dreams. Don’t waste time on something you never wanted. Do the unexpected,” he continued.

By the end of his speech, the entire crowd was in tears, totally touched by Sef’s inspirational words!

“I heard people around us starting to cry, and it surprised me because I started to too,” his mother Vicki said.
