"Most people think time is like a river that flows swift and sure in one direction. I can tell you they are wrong. Time is an ocean in a storm." - Prince of Persia: Sands of Time
How time has passed by. We never stop to realize it. Until something happens which changes the graph of your pace of life downwards and it seems like your in a whirlpool of your own stream of life and everything is at a standstill or in slow motion around you.
Its like you went back into time and see yourself and everybody who were with you at a certain point of time back to how you and they were before. Thoughts go at the speed of light in your head, some things you wish were different, some things you feel you would still like to have and some things you feel like forgetting. Something as trivial as the way you used to dress feels stupid to you. People you used to love seeing you as you were. Our mind objects that we could have done something different to take their attention or that things shouldn't have gone the way they are now.
But in the end, it doesn't matter. You were what you were, you are what you are. What you had done or been back then is the reason you are here now as you are.
Its said correctly that time doesn't wait for anybody. It just passes by. Its the nature of time, it's essence. And we are foolish if we think otherwise. And we have all been foolish at one or the other time. Its Human. Like the way I'm feeling now.
Sentiments, feelings, wishes, yearnings, all different words of the same nature.
