The epiphany came to Acooa Ellis of St. Paul right after she asked her kid the most mundane of questions: "What did you do at school today?"
She remembers her loquacious boy, Asa, responded, "We played a game. Do you want to play, Mommy? It's Duck, Duck, Gray Duck."
Ellis, an Iowa native, had never heard of this oddity, so she pressed Asa for more details. "He started to describe it," she recalls, "and I said, 'Baby, that's Duck, Duck, Goose.' "
"No, it's Duck, Duck, Gray Duck," he insisted.
And so it began. A household torn asunder over the most popular children's game in America, and an "aha" moment for one Minnesota transplant mom.
"I just looked at my husband and I'm like, 'Oh, he's officially a Minnesotan,' " Ellis said. (On the goose vs. gray duck debate, she got no sympathy from her spouse, Jeremiah, a seventh-generation Minnesotan who claims "the game has no other name.")

When your toddlers transition from calling you "Mommy" to "Mom," you know they're growing up. When they come home telling you about gray ducks, you know you're not in Kansas anymore. (Or Oregon. Or New York. Or Alabama. Or any of the 50 states except this proudly defiant one right here.)
On Twitter, I put the question to Minnesota transplants who are rearing children, "When did you realize that your kids, for better or worse, were definitely Minnesotan?"
