You know that feeling when the hands of a clock seem stuck?
Ticking away the moments that make up a dull day
You fritter and waste the hours in an offhand way
– Pink Floyd “The Dark Side of The Moon”
You know how it is. You could be at work, or at school or even at home: you have things to do, but they don’t hold your attention. You can’t concentrate. You look at the clock and you can’t believe how little time has passed since the last time you looked. It’s as if the hands of the clock are moving in slow motion, or have stopped altogether. As Shakespeare put it, time “creeps in this petty pace.”
