realizing the life

I often see that people saying "what rubbish is his/her choice".
If one likes one song, and other says what the shit you are listening, then the
person saying this is shit itself.

Everything is relative, nothing universal. for one it is good, and for others terrible.
It's human nature.
Remember  "Theory of relativity" by Sir Einstein....
It applies here too.........

And if choices of everyone become same, then imagine the face of world..
