A woman marries the man of her dreams, but on their wedding night, he insists on keeping the lights off and staying under the sheets.

She finds it a little odd but assumes he’s just shy and doesn’t think much of it.

Over the next 30 years, they build a beautiful life together. They buy a house, get a dog, and raise three wonderful children. But there’s one thing that still bothers her—her husband always insists on keeping the lights off at night.

One evening, curiosity finally gets the best of her. Determined to figure out why, she hides a flashlight under her pillow. Just as things get cozy, she suddenly throws back the sheets and shines the light.

To her shock, she discovers something completely unexpected.

Furious and feeling betrayed, she starts yelling. “How could you keep this from me for 30 years? I trusted you! I feel like such a fool!”

Her husband sighs, waits for her to finish, and calmly says,

“I’ll explain this if you explain the kids.”
