Brady Campbell’s dad Brandon Campbell, passed away after a six-month battle with Stage 4 colon cancer.

He promised his dad that he will take care of his mother.

His mother told CNN that he insisted on selling lemonade, outside their Denver, Colorado, house and told family members he wants money to take his mom on a date.

“I think he kind of came up with it himself,” she said, “so very sweet.”

Brady and his dad were making plans to open a lemonade stand for weeks and had made the signs together.

“It just never really happened because it was raining or Brandon was feeling too sick,”

Brady told CNN affiliate KDVR: “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.” 

Family and friends showed their support and a Denver police officer stopped to get a look at what is happening.

“We had fire trucks and police cars and tons of officers and firefighters and they let him spray the hose and took him up in the big tower and he just had a blast, Brady’s mother said.

“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.“

“My husband would be proud because he was a very successful businessman, so I’m sure he would have loved that.”

She said her son made  $244 dollars selling lemonade.

The mother and son haven’t gone on date yet but Mrs. Campbell said her son has plans.

She said: “He’s kind of scheming with a friend of ours, of what he wants to do,” 

“He does want to take me out every week.”

She said that her son is a very strong boy and he is happy that his father doesn’t go through the pain of cancer anymore.

“He’s been tough and he’s been more concerned about me,”

“He just says ‘I’m glad he doesn’t have cancer any more. I’m glad he doesn’t have pain,'” 

“That brings, I think, Brady a lot of peace.”
