We see the world from a perspective different to others, a view unique to you own self, a vantage point where only you can stand at. It is because no one has the same past as you. No one had the same experiences as you.
As you meet people in life, you like some and you love a few. But do you really do that?
or is it just an illusion, something only you can see, due to your past. Would still love the same person if your past was different? if not, does it exist only in your head?
When you see that person, something inside reminds you not to leave him/her ever. And the same thing may not happen in his/her mind. Its the past experiences of the other person that makes them have their decisions. They might not want you. And it hurts. When it hurts, the connections get lost. The past has been expanded. You have a new past now. You will love another person whom you might not with your previous past.
With the new past, you are a new person and the previous love might like this new past of yours and wants you. But your new past doesnt. And this hurts them and their new past forms.
Everyday, every second a new past is being formed. Depending on that, new wants arise. So the important question is
What do you really want? Now!
