Ji wrote his letter. Then he put it in the envelope and said

Then Bill stood up and walked to the door.

So tut tut said to him

Are you going out?

Bill said

He opened the door.

Tut tut said

Please put my letter in the box in the office.

And ... he stopped.

What do you want now? Bill said to him.

Ji looked at the envelope of his letter and replied.

What is your girlfriend's address? There are two soldiers in the barracks, one is George and the other is Bill. George asked, Bill, do you have any writing paper and envelopes?

Bill said: Yes. Then he gave George writing paper and envelopes.

George added, I don't have a pen yet Bill gave him the pen again. George began to write letters. After writing, he put the letter in the envelope and asked, Bill, do you have any stamps? Bill gave him one.

Then Bill stood up and walked to the door. George asked, are you going out?

Bill said: Yes. Then he opened the door.

George said, please drop this letter into the office mailbox for me, and then ... he stopped.

What else do you want? Bill asked.

George looked at the envelope and said, what's your girlfriend's address?
