Fun Story

A handsome man walked into a hotel. Interestingly, on that day, it was the hotel owner who attended to him. Then this conversation began between them:
The client: Is Room 109 empty?
The owner: Yes, it is.
The client: Can I book it?
The owner: Yes, you can.
The client: Thank you.
The room was booked and fully paid for. But before the handsome man went into the room, he asked the hotel owner to provide him with a black knife, a 39cm long, white thread, and an orange weighing exactly 73g.
The owner was surprised at the weird things the client asked for, but he chose to swallow his fear and pretend not to care — he provided all that was asked, and the client went into his room.
After midnight, the hotel owner heard strange voices and noises in that client's room. They were similar to voices of wild animals and of utensils and dishes being thrown on the floor. The owner could neither sleep or knock on the particular door that night. He kept thinking and wondering what might be the source of the noise.
In the morning, when the client handed the keys to the owner, the latter asked to see the room first. He went to the room and found everything alright. Nothing unusual. He even found the white thread, the black knife and the orange on the table. The client paid the bill and gave the bellboys a very good tip and left the hotel smiling. The owner was in a shock but he didn't reveal what he heard to the bellboys. In fact, he started to doubt himself.
After a month, the client showed up again, and requested for the same things: Room 109, a black knife, a 39cm long white thread, and an orange weighing 79g. All was provided, as the hotel owner became more curious.
The hotel owner did not sleep that night. As expected, after midnight, the same voices and noises started. But this time, the noise was louder and more indecipherable than the month before. The owner of the hotel became more frightened, and could neither knock on the door nor open it forcefully.
Again, before leaving the next morning, the client paid his bill and left a large tip on the table for the bellboys. The smile didn't leave his face.
But the owner had no smile to share. He started searching for the meaning of everything the client asked to have. Why did he ask for Room 109? Why the white thread? Why the black knife? Why the orange? In fact, the owner did not arrive at any convincing answer(s) to all these questions. Instead, he was eager to see the client show up again in his hotel, in the coming month. Maybe then, he would be able to put the pieces together.
To his surprise, on the first day of the next month, the same client showed up. He asked the same questions, wanted to book the same room, and wanted to have the same things as before. All was provided. The hotel owner remained curious and alert, and at night again, he heard the same noises. This time was worse, as the noise was louder and more terrifying than before.
In the morning, when the client was leaving the hotel, the owner apologized politely to the client and asked to know the secret behind the noises in the room. The handsome man put up a smile and replied;
"If I tell you the secret, do you promise to never reveal it to anyone else?''
"I promise I will never let anyone know about it."
"Swear,'' the client demanded.
"I swear, I won't reveal your secret.''
So finally, the client whispered his secret into the ears of the hotel owner.
Fortunately, the owner is a sincere person, and till today he hasn't revealed this secret to anyone. When he does, we will be the first to let you know...
