Millions this weekend celebrated the unofficial start of summer honoring those who gave their lives in war, and Memorial Day transcended generations at the Dallas-Fort Worth National Cemetery.

That's where Joseph Brunson, 7, bypassed barbecues and swimming pools and took time out of his weekend to place flowers on the graves of our fallen heroes.

The nonprofit group "Remember Heroes" places floral arrangements at the grave sites of local war dead each year. Joseph heard about a volunteer project at his Cub Scout meeting. The boy told the CBS Dallas affiliate that he wanted to volunteer his time alongside his grandfather, who is a Vietnam War Veteran.

"The second I heard them say, 'Memorial Day weekend we're going to graves,' I said, 'Let's do it!'" he said.

The young boy then reached out to his grandfather, Jimmy Brunson, who now lives in Omaha, Nebraska. The gesture moved the war vet to tears. "It meant that he cared about so many people who have given their life for our country," Brunson told station KTVT.

The time the two spent walking around the grave sites honoring those who gave their lives for their country was in stark contrast to the treatment the elder Brunson says he received upon returning from war.

"I thought coming home would be great but the airports were bad," he said of war protestors. "It made you want to forget everything."

The weekend with his grandson will certainly prove memorable. "This is a great thing our nation has done," Brunson says of Memorial Day. "I really appreciate it. I really do."

Neither the Brunsons nor Remember Heroes has responded to ABC News' requests for comment.
