When Luke, a 6-year-old boy, came back from school one day, he was overly excited to share with his mom that he had found his twin sister at school.

“Mom,” Luke started, “I swear…”

“What did we say about swearing?” his mom, Amy, asked him.

“Mom,” he continued, “I’m telling you, Luna is my twin sister!”

“Luke,” Amy responded with confusion, “You’re an only child, honey.”

“No, Mom! I’m serious. Luna and I have the same birthday, and we look alike. The teachers think that we’re twins, too,” the boy insisted.

For the rest of the day, he wouldn’t stop talking about Luna, her likes and dislikes, her favorite things, and more.

As Amy kept reassuring him that he was an only child and it wasn’t possible Luna to be his sister, Luke went to his room and grabbed the class photo. Amy had seen that photo before, but she didn’t pay attention to the rest of the kids.

When she saw Luna, she was a bit shocked. The resemblance between her and her son was uncanny.

Knowing there could be something behind this rather than a pure coincidence, Amy asked Luke if he wanted them to invite Luna and her mom over. Luke was over the moon.

“Do you think she’ll come?” Luke asked. “Like really come over?”

“I’ll speak to her mom tomorrow when I drop you off,” Amy smiled to her son.

When her husband Jeff returned home from work that night, Amy didn’t mention anything to his because it was too late and she had forgotten all about it.

The following morning, when she dropped Luke to school, Amy met with Luna’s mom, Penelope and the two arranged a playdate.

“Luna talks about Luke all the time, Amy,” Penelope said. “This will be great for them to spend time together outside of school.”
