Meet Frank Diaz, Fresno city garbage man. Every day he loads into his truck, drives through neighborhoods and picks up trash with pride.
It's his job, his livelihood, and his passion.
"I love the community, everything that we do is for the community, I grew up in Fresno."
Little did Frank know that his work carried an incredible impact. His day's duties became a weekly treat with extraordinary bearing on this family.
"He shows me that things are going to be okay."
Every Wednesday afternoon 4-year-old Greyson Kelly runs down his driveway and waits patiently for Frank to come by. The roar of his truck sparks excitement, feeling.
Greyson can hardly contain himself. It's his way of communicating, something that often doesn't come easy.
"You see the way he reacts. He lights up, his entire body feels joy."
Greyson has autism. He doesn't talk much and his parents struggle to get inside his head. But Frank and his big shiny truck broke into the little boy's world.
"He heard it and said, 'I want truck,' and I was blown away that not only did he hear, and process, but he said three words to me ."
This has been Greyson's and Chrissy's weekly routine for two years.
Recently they met the man behind the wheel. Frank stopped his truck and invited Greyson inside.
Chrissy shared the magical moment on her blog. "Sometimes I worry about how people will treat my boys, and today was a beautiful reminder that people are good all because of you Frank."
"I honestly didn't know that I made such an impact on him and it touched my heart."
A simple act of kindness that turned this garbage man into a hero and a friend.
"What does Frank mean to me? Frank is a representation of everything I try to look for life and that there's more good than not good and Frank gives me hope in the world."
Frank's been impacted too. He says he's now a better person and his Wednesday route a little more special.
"There's more joy in it now, every Wednesday I look forward and I have Greysons' picture with me everyday."
This story has gone viral. So far, 15,000 people from about a dozen different countries have read the blog Chrissy posted about Frank.
