People shared the most unforgettable moments when their partners said or did something so shocking they couldn’t stop thinking about it. One person discovered his girlfriend had been secretly plating fancy takeout meals because she didn’t know how to cook but didn’t want to disappoint him. Another found out his girlfriend genuinely believed opening the glove compartment could “damage the engine,” while someone else learned her partner dumped all her q-tips loose into a drawer because he thought throwing away the box would “save space.”

Some stories were hilarious, some concerning. One person’s partner tried to heat their apartment by running the gas oven with the door open—windows shut—without realizing the carbon monoxide danger. Another proudly waved a $5 lottery win after spending $20 on tickets. One woman ended a long relationship only for her partner to ask, “Why did you ever kiss me then?” as if two and a half years hadn’t happened.

There were moments of pure confusion too: a man tattooed the Louis Vuitton logo on his own cheek backwards because he forgot reflections reverse images. Someone else’s girlfriend panicked when she saw the sun and moon out at the same time, thinking they were always supposed to be on opposite sides of the Earth. Another person dressed as Death for Halloween, and his date asked if he was a farmer.

And then there were the unbelievable beliefs, like a partner who thought microwaves worked because of “tiny people inside.” These stories remind us that even the people we think we know best can surprise us in ways both funny and bewildering—and sometimes those moments stay with us forever.
