looking back doesn't help always

i have realised this now... but not when, back in childhood, we never went back to a certain place we had stayed long enough to have fond memories. the logic was, we would not be able to relive those moments... people change, Dad said, so the revisit would only leave us crest fallen...
the hope with which we look back, the nostalgia that we cherish is only good for the memory... it is best not to rekindle hopes of getting the same flavour back with those same people, since people change...
i tried to link up with lost friends, many a times, in the hope that i would have the same feeling when the relationship was initially there... in no case has it happened that i could savour the same flavour... possbly the miles we walk thorough life leave indelible impressions on the psyche, so either the friend you rediscover cannot excite your thoughts any longer or has become so very different that the original wave length is lost... and let's not forget, he/she may be feeling the same about you... afterall, people change...
