A 6-year-old Denver boy opened up a lemonade stand earlier this month, one day after his father died from cancer.

Brady Campbell’s stand fulfilled a dying wish from his father who lost his battle with colon cancer on July 7.

"My dad and I came up with the idea of 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," Brady said, according to FOX 31 Denver.

Campbell’s stand caught the attention of a Denver police officer who called in other first responders.

“It was amazing. You could just feel the warmth and energy and such a positive thing in such a tragic time for us. It really lifted our spirits and really made Brady so happy. Brandon was a savvy businessman and wanted to teach Brady all those lessons, and I could just [see] it happening. It made my heart really happy," Brady’s mother Amanda said, FOX 31 reported.

The stand raised $244 the first day and a virtual GoFundMe lemonade stand has brought in more than $12,000 to continue the mother-son dates and for cancer research.

Brady plans to make the date with his mom a weekly occurrence, the station reported. For their first one, he said they may go for sushi and ice cream.

“Maybe we will have our Friday night date night. Brandon and I used to do that, so I think we will start that and take the time to spend that time together," his mom said. "I feel like [the lemonade stand] gives some purpose to such a tragedy," she said according to FOX 31.
