Everything fades, as times passes by, If people are aware of the fact that change in life is inevitable, be it with people we possess or things we own, the more at peace they will be. There comes a point in life where you turn numb to all the drama around you. One thing is very certain, the characters may change but the drama continues all through our lives and the most ridiculous part is that we too play some roles in other people's play.
These things are realized by every soul sooner or later in their lives. As the saying goes, 'The sooner, the better' holds good very much in this circumstance. I can state examples from childhood till our deathbeds where we keep changing in every form physically and mentally. Everything changes, the places we go to, the people we are with, the things we use, etc. One thing remains forever, "memories". But I feel it is just a myth because as time passes by, we tend to either bury them too deep in our hearts wherein we even forget they existed within us until they are re-kindled, or we force ourselves to forget them just to free our minds by overthinking them and causing more hurt at that time rather than when the incident actually occurred.
Leave alone mankind, even God keeps changing! Yeah, trust me. People worship so many Gods that have evolved during these many centuries. But myth or mystery, we all tend to believe one form of God or the other. The creator Himself changes in inventing new species. There is hybrid in everything now, inventions of mankind or God instigating such thoughts of inventions in our minds. Only species left is our mankind where 'hybrid' has not yet been implemented.
When a person realizes these facts in life, he attains a position where he can find peace at anything and anywhere. Change is inevitable folks. People do change, some for their own needs, some due to your actions. Whenever a person walks away from your life, just know that their chapter in your story is over and that God has started writing a new chapter in our lives. Also whenever you lose something you always gain something better, but terms and conditions do apply here! Provided you are not at fault due to your actions and you do not hurt anyone in your story. Just imagine five years ago, if you still have the same set of people with the same kind of feelings or relationships they had with you, then you are Lucky. But remember, not for too long because when you look back at 10 years, Everything would have certainly changed. If you see them remaining the same, then it is out of mere force or selfish needs are some things and people remaining the same.
