Which activities make you lose track of time?

I guess it depends on how you define activities. Sleeping certainly makes me lose track of time. But sleeping is not an activity, you say. So I say, what about sleep walking? A track to walk on, and sometimes sleep walkers lose track of themselves, and hands of the clock lost in the dark ahead of them, on they go, tick-tock, little clockwork soldiers marching until someone or something wakes them up. Where am I? They ask. And what time is it?

Watching my fox terrier chasing his tail as he runs round and round in circles, never quite catching it, but never giving up his high hopes of catching that little rat-tail of a tail that dangles there behind. And round about and out and in all day that silly dog did spin, spinning in prose and spinning in rhyme, until I lost all track of time.

Same thing happens with that little electric railway that ran on a single loop around the kitchen table. Diddle-da-diddly-da, just like a real train, except no smoke, no puff the magic dragon, no sense of a schedule or arriving and departing on time, when circular time is meaningless, as are the numbers on the sundial when the sun isn’t shining, or the hands on the clock when the numbers are missing, and you don’t know whether you are looking in time’s mirror or are standing on your head in the Antipodes and all the while the clock hands are marching round and round, tick-tock, and there is no track by which time can be tracked. And the runaway hands went round the track and the ghost train hooted whoo-hooo, as it vanished into the timeless tunnel of darkest night, and then exited. like Rip Van Winkle, the engine driver with a huge beard, and the carriages all covered with cobwebs and skeletons peeping out of the compartments and sitting beside some of the travellers as they snore on their seats.

And wow, the activity, if it be an activity, of walking my fingers over the keys has just made me lose track of the last ten minutes. And now it is time for me to drive to hospital, have a needle stuck in my arm, and allow a nurse to draw my blood. And the moment from the first sight of the needle to the moment it is withdrawn from the end is e-n-d-l-e-s-s and takes an eternity.
