I hope you must have been on a slide. For those who have not been on one ,
1)You climb up to the slide
2) You slide
3)You climb out of the slide.
So which is the best part ? Ya it is the second one when you slide. When you slide, you only enjoy the present and let every other thing go. That is what makes the ride so enjoying.
The slide signifies our present which is very short lived and must be enjoyed. However we spend most of the time climbing up the slide ( Our Past ) and Climbing out of the slide (Our Future).
To Quote a paragraph from 100 Years of Solitude, " In the shattered schoolhouse where for the first time he had felt the security of power, a few feet from the room where he had come to know the uncertainty of love , Arcadio found the formality of death ridiculous.Death did not matter to him but life did, and therefore the sensation he felt when they gave their decision was not a feeling of fear but of nostalgia. He did not speak until they asked him for the last request."
