I always feel like a bit of a time traveler on my birthday. Of course we're all time travelers, going in one direction, but I usually don't think about it. On special occasions, however, I travel into the past in my head, missing all the people who aren't with me any more on my continuing journey, but cherish their memories. Not at all like the TARDIS traveling around London and mashing it up with Google Street views (thanks, TMS!) but there you are.
