“He’s funny, he’s nice, kind. Smart,” Brady said.

Brady says he and his dad came up with the idea for a lemonade stand.

“To take my mom on a date. Because I didn’t have enough money and I wanted to pay. So I did it,” the 6-year-old said.

The day after his father passed away this 6-year-old followed through on his promise to take care of his mom.

“Brady is a very sweet soul. He’s always looking out for everybody else and I think he really learned that from his dad,” his mom, Amanda Campbell, said.

His neighbors and friends came by in the crowd caught the attention of a Denver police officer once he heard Brady’s story, he put out a radio call to other first responders.

Fire trucks and police cars started rolling up.

They raised $244 that day.
