Larry Bright holds his 3-year-old son's hand while the boy steps through a leafy playground in Silver Spring, Md., and practices counting his numbers in English.
At the top of the slide, the boy begins counting in his other language: Vietnamese.
Bright, the boy's father, is African-American; his mother, Thien Kim Lam, is Vietnamese. The couple has two children.
"They are a perfect mix between the two of us," Lam tells Arun Rath, host of weekends on All Things Considered.
