A/N: This one is actually about The Doctor. I love him, so yeah. Oh, and it's a sonnet
Your knowledge is brilliant but a bit odd
You are old, but you don't appear to be
You know much of this world and far beyond
You are very, very special to me
As the years go by, and the days are done
We cannot be together for all time
I will always love you, you are my one
I still wish that you could always be mine
You spend most of the time travelling
You cannot always take me with you
Often you leave me wondering
If you will come back as someone new
Although you may change in many ways
We'll always share love to the end of our days
