A Massachusetts father was shaken when he returned home from work and saw that a door he typically leaves open was closed shut. Inside his house, he smelled chemicals and knew someone had broken in.

Except he learned the stranger who entered his house without permission didn't steal anything, but instead cleaned it.

Nate Roman told CBS News that the May 15 incident initially made him panic.

"I went into protective parent mode when I saw that my son's room had been cleaned and called the police,” he said.

"It's possible that I forgot to lock the back door, they didn't break anything while entering," Roman explained on a Facebook post . "I usually forget to arm my alarm during the day, but unfortunately that also happened, so I don't have any video, despite having cameras."

"Ready for the weird part? Not only did they not take anything (that I can find), but the purpose of the visit was to clean my bathrooms and bedrooms. They made the beds, vacuumed the rugs, scrubbed the toilets and left [toilet paper] roses," he wrote.

Roman, 44, inspected the house and found that every room had been cleaned, except his kitchen. Even his five-year-old son's bedroom, which had been left messy, was now immaculate, complete with his stuffed animals being neatly arranged.

The pièce de résistance, however, was the carefully folded toilet paper in the shape of a rose.

"I'm pretty sure, based on the quality of the toilet paper flowers, that this was a professional that made a mistake," he told CBS News. "But there's no way to really know."

Police confirmed to CBS Boston that Roman called them on May 16 to report a breaking and entering. Even after speaking with neighbors, who claim they saw nothing suspicious, there are no suspects.

Roman’s Facebook post left many social media users wondering how they could get a benevolent person to clean their houses.

"I wish someone would make that mistake in my house," one person shared. Others chimed in that they would leave their door unlocked in the future.

"I wish someone would come clean," said Roman. "Pun absolutely intended."
