Weather keep change time keep change year keep change Nature keep change.
One thing always be stay in you is heart that will stay at the end of life.
People will only change if some sudden happen in anybody life or something that disturbs but then also I feel that nature of person not change it will change for a moment or for some time but not permanently. The habits which people do they will stay . The habits can be changed only when its repeated we all usually bored and move on and search new thing or get that new thing .
New things that found us feel us great,different, new we love to be that but obviously not all things that we love will be stay as we want. But one things stays with us is our nature our thinking power our heart will stay until we survive in this world.
