Jokes on who?

Have you ever heard a joke so many times you've forgotten why you found it funny in the first place? and then you hear it again and then it hits you and you can remember why it made you laugh? Possibly its because I'm so tired due to lack of sleep that I see things clearly now and realise how that there are certain times in life where time can feel like it stands still, such as love at first sight... that's something everyone know's but what you have to realise is that after time stands still, after a while the world races to catch up with everything else. Backstepping through all these years without certainty, sleep deprevation has aided in clear visual thought and that's what the joke is here..
