Past is so different then present and future. Past is gone its over , present is reality and future is a dream.You can just remember past and realize that you dont even know where people are who were with you in past. you realize you dont even have failed to sustain relations which were important, you have failed to understand changing ways of life...

But you don't try to go back and mend ways, because there are no mending ways. Past is over and present is your life. you just try to make sure what went wrong in past dont go wrong in present.
You just wish everyone who was part of your past, remains happy, satisifed and content with their present and you try to do that with your own. You just wish that relations you have right now become better in future.

In life there are permanent friends if not permanent enemies. There are people who will always think good for you , will want you to be happy, even if they dont talk to you, even if they are no more part of your life, you just think and pray same for them.

Because life is a long journey with falls and climbs.....
