"Gma" is on the road as you know live from Houston. Michael, Lara, ginger are there. Michael, this is all to honor a really incredible Houston hero. Yes, robin, we have so many incredible hometown heroes in Houston. We're feeling the love here this morning from this awesome audience and crowd that we have here in the park. And we have someone here who is really special. We want to celebrate him. A 12-year-old boy made it his mission to feed those in need. Let's give it up for math true reel and his mom Tammy, everybody. Welcome to the show. Tammy, welcome as well. This summer we've been traveling around the country looking for hometown heroes doing good things for their community and heard about what Matthew here is doing helping others and now we want everybody else to hear about it as well. So take a look. That little boy can shop on a budget. He had a young woman walk up to him once and said I want to help but I only have a dollar to spare. Matthew reached over, hugged her and said, ma'am, do you know what I can do with a dollar? Reporter: You'll never meet a young man as generous as Matthew. Reporter: He was 8. We had attended a church function and they were making blessing bags to hand out. We drove up to a man and handed it to him and the man said god bless you little boy. He said, mom, I don't want a birthday party this year. I don't want presents. Reporter: He wanted to feed those in need and that's what he did. Stretching his dollars eventually realizing those closest to him needed the help the most. He goes I think I'm supposed to be helping the kids by to school with. I met him and he talked about providing meals, healthy meals for families in his own school. It has spoken to other students to give to their community as well. Reporter: Setting an example for those around him, inspiring other kids to follow in his footsteps. Matthew came and spoke to jack's cub scout group last fall and told us about his program that he started. I wanted to give back to every kid. Reporter: And the impact of a 12-year-old turning a simple gesture into a movement, something we can all learn from. The least we can do is give them a can of food. We can take away some of that pain and hopefully when they're in a better place they'll feel the need to be able to pass that on. And, Matthew, you are a special young man and, Tammy, you raised a special young son. You've done so much for the community. But you're not stopping there. What is your ultimate goal. So my ultimate goal is I want to -- so backpack program is where kids go after on Friday, get food and bring it home to their families that are in need so I want to be the first student run backpack program where kids donate the food and then the kids in that school district get the food back. Wow. Tammy, as a mom, you must be really proud of Matthew. I don't like to use the word proud. I hike to say humble. He looks at the world in a completely different way than anybody else does and to be able to walk in his shadow and see his care and compassion for those that are in need, it's an awesome thing.
