I tried doing that and i was quite shocked at my own outcome . I started my whole process of relating to reality with thinking what is the importance of each of them in language .Yes , one is to give a break , a pause and another is to end it all , to be precise .Very similar to their usage in language is their role in day to day life . You sleep every day what would call it , a comma or a full stop , you make goal and work towards it every day , and once you achieve it you stop working towards it what would you call it ?
There are a lot of things in our lives which are in a state of a comma , that how we think they are , but some how we realize sooner or later they have taken a shape of full Stop.they are so many things that we keep pending for future , thinking we shall take a break and start all over again , but gradually their existence washed away , and they are never started . while there are instances and moments that we have accepted that will never come back again , and have ended for ever , but they never seem to go , People who keep influencing your lives no matter how much you want them to go , they keep coming back it seems there is no full stop to them in your life .
But the point i wanted to make is very different , by now i would have made you agree that these to punctuaationn marks are ite importanat in your lives as much as they are in English Language.
Just as you can understand a English sentence in a incorrect way ,by misplaced comma and full stop marks your life can totally take a different shape you "full stop" a never ending task .
