Luke was a six-year-old boy, who shocked his mother, Amy, when he said that he has a twin in his school.

For many years, Amy had the great life with Jeff, and son Luke, where they were having great time as a family.
One afternoon, as Luke came back from the school, he talked about his day to his mother, Amy.
“Mom,” Luke started, “I swear…”
“What did we say about swearing?” Amy asked to her son.
“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.”

As Amy continued to cook, Luke kept talking about Luna, about what she would like to do, to wear, to eat, etc.
“Mom, she’s great. You’ll like her!” Luke said then.
As Jeff was not at home yet, Amy thought that Luna was a special friend for Luke.
“Do you think you have a photo of Luna?” She asked to her son than. Luke ran to his bedroom, and brought the class photo. When Luke pointed Luna on the picture, Amy noticed that even though she had seen the picture before, she never noticed anyone else than her son.
But Luna’s resemblance to Luke was uncanny, as also her mother-in-law was confused with the resemblance too.
“Why don’t we invite Luna over?” Amy asked to Luke. “If her mom is okay with it, then you two can have a playdate.”
“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 Jeff returned from work, he was too tired, and they didn’t talked about what happened that day. As Jeff directly went to bed after dinner, Amy couldn’t sleep. As she struggled, the morning arrived.
Penelope was Luna’s mother, and Amy met with the woman after she left Luke at school. Then they 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.”
When the day arrived and Penelope brought Luna for the playdate, Jeff was home too. When he saw the freshly baked cookies, he asked, “What’s going on? We’re having people over?”
“Yes,” Amy said. But she decided not to talk about the situation, as she was suspicious of her husband.
As the door got knocked, and Luke opened the door, Luna rushed towards Jeff as she saw him. Jeff went pale with the scenery, as he saw Penelope and Luna.
