A mask hides the wearer's identity, creating a barrier between the observer and the person behind the mask. This anonymity can be unsettling because it strips away the ability to read intentions or emotions, fundamental aspects of human interaction.

we think too much and feel to little.
"Charlie Chaplin"

I think nowadays it is very important for a person to hide his true self 
Unfortunately, I am a person who does not have this trait, and unfortunately, I always get hit by people
I wish it would disappear🎭
