Well answer to this question is not so straight forward... Yeah sometimes we have to change but it doesnt mean we got to forget ppl who are not around you.. Things could'nt be more worse than this...
After all we are humans all with bad memory so we tend to forget... How does changes change us... no way it change us the bitter truth is we get changed..we keeep moving... We start liking the new change which might exist for a long time and we get lost in it that we dont try to come out of it.. Which sometimes is expected and needed too as we try to forget the bitter past not the sweeter one... As far as life is concerned we do need to consider the past not just the change.. Consideration as in remember the past which had has taught the real meaning in life... the real value for life... ppl who really loved us and who still love us even in our absence... who always wish for our excellence not just success...
But what we do is we easily forget these things for the change we accept in our life for the current situation.. saying that "wat ever be the life must go on"..or "life is a choclate box dono wat we might have"..but we should know which was good... Sometimes it becomes worst when we lie that we really missed our past just for consoling others.. which we really dont as we hav adopted and used to enjoy the new/change without even realizing the fact that we are hurting our own relationships.. just for the change :(
Though we might argue on this sayin we dont.. but we know it is the fact and we do it without our knowledge sometimes...
Changes can change us !!
