“I wanted to teach them about American history and the meaning of Memorial Day,” said James.

Every year, James attends the ceremony to honor two family members killed in World War II. His son, Tony, is named after his fallen uncle Anthony Pareso.

Tony taught his oldest son, Jason, that Memorial Day isn’t a holiday for pool parties or barbecues.

“They put themselves before others in the war to help other people survive and be free,” said Jason.

The young boy is old enough to understand the significance of Memorial Day. His younger brother Cody also understands, but had trouble finding the right words to explain his pride.

“There are ‘veterinarians’ in WWII who died for us,” said Cody.
