In the news, it was reported that this Chinese woman, or Vietnamese woman, forget now, who could not speak English, went missing from a Toronto hospital.She was a middle aged woman and a patient there. No one knew where she went, and her family did not know either.
Then the next day, as a repair crew came to fix the elevator, they open the doors and she walks right out. Since she did not speak English, no one knew what was going on.
She spent 24 hour or more inside the elevator. She was alright. This was not some service elevator either, away from people.
Who knows. Maybe went some people get trapped, they go nuts.
