Japanese art of minitiarization is very famous. But I still was shocked by this story. This lady became homeless and wandered into a house of this guy. She had no place to go so she called one of his shelf closet her home.
She had been living there for a year, taking baths and eating his food without him knowing it!! Ultimately, when the food started disappearing a lot, the man grew suspicious and installed cameras. But no one came from outside. So, they kept looking until they ripped open the closet and there she was all curled up neat and tidy!
