Please remember that when I wrote this I hadn't seen the episode with Sexy, the one with House; I did a little editing and I hope you like it. Okay, so as much as I wish I was a Brit and really rich and the mastermind behind DW, I'm not. Cheers!
On a forgotten street, there lies a box. A blue box. The deepest and loveliest blue you've ever seen in your life. It wasn't just any box, it was a magic box, it could take you away forever and farther; to the ends of the Earth and the beginning of time. It was a box that was made on the hopes and dreams of all who came across her. Now this is no ordinary box as you may have deciphered. She was special, she would love you and care for you as long as you gave him a hand to hold. As long as you stayed with him she would stay with you and love and care for you but when came the time you leave, she never really left and you never really left her beautiful, beautiful insides. She never wanted to stay in one place, she longed to travel and be free and say, "Hello".
She had a companion of course, one tends to get lonely after years and years, oh those brilliant years. Sometimes it was just him and other times it was him in another, sometimes one sometimes 2, 3. She had too many to say who she liked best, and she got lonely without them but, her Thief would get lonely and take new friends to travel with them. They understood each other, her and her Thief, they only had each other constantly. They were both the last of everything they once held dear.
But as was said in the beginning, now she is all alone. Her and her Thief's days are now over. No more traveling, no more saving the day, no more happiness brought from their brilliant adventures. No, now she has been forgotten on the street with no name, on the planet that never belonged to her or her... Doctor. No one would understand. They couldn't, they could spend the short forever with her that she had and couldn't begin to touch the bond of her and her lovely, lovely, lovely, silly Doctor.
The TARDIS and the Doctor. Both of the last of their kind. Together forever. The plan was to help people; in the end go out with a bang and leave a legend. Only one of the two went out with a bang, the biggest bang ever. Bigger than the first bang, the biggest bang was only suitable for her Thief. He has gone but she remains, on the lonely street corner, dying.
The Doctor has a habit of changing and shaping those around him. For better or worse. He is gone now but we remember. But we do not say goodbye. To say goodbye is the leave behind and to leave behind is to forget. So we will not say goodbye to the Doctor who said goodbye to us.
The turn of the minute, second, hour hand. The forgotten street with the lonely box is the same until with a groan and a flashing light, the bluest of blue box fades. The TARDIS and her Doctor traveling the stars. And all is as it should be.
