Multiverse

The following conversation happened between a Physics major and a Random guy on a High --

A = Physics guy
B = Random guy

A : Dude, do you know about the multiverse theory in Physics ?
B : Nope, what's it ?

A : It was given in relation to Physics by Max Tegmark and says that there are multiple parallel universes and not just one. And basically whenever in life you are given choices as many Universes are created each pertaining to each choice.
B : Interesting ! You know such stuff already exists around us

A : How ?
B : Every time something happens to us, it changes us. And the change is so complete that you are no longer the same person. You can never go back. Of course changes vary but sometimes these changes would be so profound yet so subtle that you'd never have realised how something changed you...forever..how much ever you deny the existence of that change ! They'd be like an irreparable damage to your core.

A : what kind of change are you talking about ?
B : anything , something you gained, some loss. let's talk about loss, I'm in a 'dark' mood :P
You know every loss would grind a hole into your heart ( don't talk about it's size with me now ! ) You'd try to repair it, fill it, It's like that BP oil pipeline Burst. Times would be when you'd be in that false security that you've succeeded, but wouldn't have. It'd comeback to suck you in at times you'd never even expect. In the end you would succeed ( BP too did ! ) in the wake of it, at times you'd find the world has changed. But actually it's you who would have. A totally new being a stranger yet not a stranger but never the same person again.

A : Hmmm, Dude! you've drunk too much !
B : I guess it was max who was High when he gave this theory !
