Tea at the Ritz?

William arrived at the Ritz Hotel carrying some roses for Anna.
He knew the room number and knocked. A bright-faced American girl opened the door. She is Karen. William was surprised to see a number of reporters and photographers, all clearly waiting to talk to Anna.
William was asked by Karen, "Which magazines a re you from?"
William didn't not know what to say. He looked around for ideas and, on a small table, saw a copy of "Horse and Hound" magazine. So, he pretend the reporters of the magazine.
He could go to the Anna's room somehow.
He could talk with Anna and give some roses.
William asked, "Are you busy tonight?"
"Yes," Anna said.
Time up!!
He went out her room. Then Karen meddled. She said that William could interview other actors.
He didn't know about the movie and he wasn't interested in them, so he confused but he did.
After the interview, William was called by Karen. And she guided him for room with Anna!
And Anna said, "I've changed tonight plan, I have to spend the evening with Horse and Hound's star reporter."
William's heart jumped.
"Oh, well, great Excellent." Then he had a sudden thought. "Oh, no! It's my sister's birthday...we're having dinner!"
He said he won't go there, but Anna said  she wanted to go to her birthday party!
