From elsewhere in The Post: An Asian father upsets his parents when he adopts an African American baby. That was six years ago, and his parents still have not seen their grandchild.

“My 6-year-old is starting to ask questions about my parents. I don’t want him to take away from our talk that he was the cause of the estrangement, that it’s his fault. Thank you for any help!” writes the worried father in a letter to advice columnist Carolyn Hax.

Hax guides this father in answering his son honestly, without getting into the gritty details of race, racism and familial estrangement.

“Given the limits to a small child’s ability to comprehend, you likely won’t have to answer the Big Question until you’ve laid a foundation of small answers,” she says. Read the rest of her response here and visit her online discussion group, Hax Philes, for more advice.
