The Doctor was in the TARDIS, walking from side to side in the console room. They had gone to Earth to visit their friends from UNIT when the Brigadier appeared with invitations to a formal dance that a high political office celebrated that night in his house. Although at first the Doctor thought reject the invitation, Sarah seemed very excited about going to the dance, so he finally accepted. Now he was waiting for the girl finished dressing.

Sarah entered the console room dressed in an elegant black dress with strapless neckline and her long hair in a discreet bun.

"How I look?", she said as she turned on herself so that the Doctor could see her full outfit.

"Lovely. Let's go", it was his answer.

"If you have not even looked at me", Sarah said disappointed.

Yes, he had looked at her. The Doctor only needed a rapid glance for not to be able to take off his mind how beautiful his companion was.

"And you could have dressed in something more appropriate", Sarah continued to see that her friend was wearing the same clothes.

"I am wearing my best shirt and my best hat", he said while they both went out of the door.

When they reached the house of the politician they saw Harry Sullivan and the Brigadier Lethbridge-Stewart that were awaited them at the door, they both elegantly dressed in a tuxedo.

The two members of UNIT greeted the Doctor and Sarah Jane.

"You are very beautiful, Miss Smith", the Brigadier said.

"Thanks. You are also very elegant, Brigadier. And you too, Harry".

"Thanks, old girl, but it seems that someone forgot to change clothes", Harry said looking at the Doctor.

"Oh, what are you saying, Harry? He is wearing his best shirt and his best hat!", Sarah said mockingly.

The young woman hardly hid that she had liked to see the Time Lord wearing an elegant suit.

"If you have finished joking about me, let's go inside. The sooner we go in before we will leave", the Doctor said walking towards the entrance of the mansion.

That was the greatest and most beautiful house in which Sarah had never been. Though after living in the TARDIS the size of the mansion not impressed her at all, she was quite sure that she could never afford a house like that.

The ballroom was filled with elegant people who danced to the waltz music that a band was playing. Sarah's eyes sparkled excited before the spectacle. The journalist took the Doctor's hand.

"Doctor, dance with me", she told her friend.

"No thanks, Sarah. I do not fancy".

"Just a dance. If you cannot dance I can teach you", the girl insisted.

"I do not dance, Sarah. I'm the Doctor, not the Dancer".

"Okay. I do not need you to have fun. Let's dance, Harry!", Sarah said dragging the young Sullivan to the dance floor.

"I think you have been a little rude with Miss Smith", the Brigadier said the Doctor.

"Oh, it is all right. Soon she will have forgotten", he said as he looked at Sarah teaching Harry dance steps.

The night passed too boring for the Doctor, who had to put up with the Brigadier stories about everything that had happened since he left UNIT: giant insects, carnivorous plants, aliens with eyes in their hands... he only heard 'blah blah blah'. While nodding occasionally to pretend a little interest, he could not look away from Sarah.

The girl was having fun on the dance floor with Harry. From where he was he could see the sparkle in her eyes, eyes that looked at Harry, and he could see her radiant smile, also dedicated to Harry. If he had agreed to dance with her that wonderful smile would be just for him.

"Doctor ... Doctor, are you listening?".

"Mmmm?".

"Do you want to dance?", the Brigadier asked.

"Alistair, I am flattered, but you are not my type", the Doctor said with a smile.

"Not with me, with Miss Smith! You have not stopped looking at her since she went to dance with Sullivan".

"I care about her. Harry is very clumsy and at any time he could make her stumble and fall", the Doctor said.

"Miss Smith can take care of herself, and it seems she is a good dance teacher. Why don't you ask her for dance? Sure you will make her very happy".

The Doctor shook his head and continued looking at his friends. Harry had to have made some funny comment, because Sarah started laughing. They made a nice couple together and it seemed like they were intimating much in one night. He knew what that meant: when his companions were in love, they left him. He had already lived that situation with Vicki, Jo, and even with his own granddaughter, Susan.

He was glad that his friends were happy, of course, but he had very fond of the journalist and he could not imagine life without her.

They were at a party, it was a time for fun and games with no more worries that receive a stomp of a clumsy dancer, but the Doctor felt sadness in his hearts. Today he could lose his best friend for having refused a dance with her. A damned dance... Why did he do it?".
