Time doesn't quite mean the same thing when you're travelling with the Doctor. Coming home and having to deal with calendars and deadlines when you're used to stepping out in to different times feels so wrong.
In the first few months after my return I felt so out of place. It was as if everything that used to be important had been buried by the sheer magnitude of my travels with the Doctor, everything I did seeming dull and lifeless compared to the things I'd done before.
I hoped he'd come back.
I waited for him but he never came.
