Bedroom #1

He walked toward Bedroom #1. There was a "T" sign on the door. John opened the door and walked in.

There was a woman in the room. Hearing the door opened, she turned back and said:

"Although you are my husband, you must knock on the door before entering."

"And if I don't?"

The woman smiled wickedly: "This is my house, and I can drive you out."

John didn't know whether she told the truth or not, so he silently turned back and went out to collect more information.
