This video from an older 20/20 ABC segment just went viral in the past couple days. ABC’s John McKenzie covers a story about an autistic girl named Carly.

Born in Canada, Carly’s parents realized she was falling behind at age two. She was diagnosed with severe autism, and, together, the family struggled with Carly’s condition for years.

Finally, at age eleven, Carly, who was thought unable to communicate at all, started typing messages to her therapists. From then on, her world began to open.
