People care too much about what others think of them instead of them not caring and just being happy they would rather just hide there natural selves away and just show it when they are alone. When people start to pretend to be someone they are not soon enough they actually become that person. And they start to loose the person they once where.So in my opinion I think that people shouldn't hide who they really are and just be happy because in life your going to get judged on everything you do so just ignore what everyone else thinks and just do you because its your life not theres. Nobody is perfect not one person can say that they are or that they have never made a mistake.
In conclusion those are just some of the reasons that I believe people tend to hide there true
