In this Wednesday, March 2, 2016 photo, Sam Alexander ties the shoe lace of his son, Ben, on their way to a class at Tulane University in New Orleans. Ben, who has nonverbal autism, is a junior at Tulane, an English major with a 3.7 GPA and a computer full of essays, one of them published in a local journal and another on the university's news site. He wants to help educate people about autism and challenge stereotypes. (AP Photo/Jonathan Bachman)
