I wrote this as a random writing warm-up but I actually quite like it.
The Doctor
has never liked endings, because those in his life are never happy. Too much
pain, too much loss, too much regret.
No matter
how much he tried, he lost them all, one by one; forever ageless and full of
life, while his friends aged and died around him.
He is
always running, staying ahead of it all, trying to keep the sorrow at bay, to
begin afresh.
But every
story must end sometime, somehow, and one day, his ending will catch up with
him.
After all,
one cannot run forever.
Everything
has its time, even for the Doctor.
