Marty Mendoza wants his son to experience everything. He bestows unflinching love on his son, Marty Jr., who is nonverbal and lives his life with seizures and severe autism. With Mendoza's ex-wife completely gone from their lives, they are each other's worlds. But Mendoza wanted the rest of the world to see what a wonderful young man his son is. He also wanted his son to know that the world noticed and appreciated him, so he went to Facebook and asked if someone wouldn't give just one Christmas card to his son. "I get hundreds of cards a day, every day," Mendoza said. And each gets the attention the sender kindly gave Marty Jr. "I read every single one to Marty Jr." The absolute outpouring of love and warmth from so many strangers overwhelmed Mendoza. Since last Friday, the Mendoza family has had a lot to celebrate. After being abandoned once, any more wounds hurt twice as much With the bustle and mayhem, the holiday season can bring, some people may feel left behind.

My ex-wife, when he was born, she up and left when he was about 2 years old," Mendoza explained.
