BIG QUESTION pt3

As I'm investigating further about my BIG QUESTION I have noticed that when people change who they are, they just want to blend in the crowd and not be an outcast well it's good to blend in every now in then but what really bothers me is ''WHY DO THEY DO IT'', being themselves that bad they have to change just to follow the crowd. I wonder what's going in their mind when they make these drastic changes to themselves.
