Sam Waldron, 23, announced to family and friends that his brother John Waldron, 27, is his “hero” and “never looked down on me” at John’s wedding. Brave Sam reveals that he has autism, because of which he is afraid to communicate with people.

His brother reminds him that “being different is a real strength, not a weakness.” The performance of the groom’s autistic brother’s best man from Iowa left the guests at the wedding, as well as millions of social media viewers, in tears and seams.
