Mask

I think the main reason why most people use a mask is because they're afraid of who they really are and what they want to be. A lot of people just want to be someone else and that's just an example of how people use a mask today. If you hide behinde a mask then you think that everything is okay and that you don't know who you want to be or if you can be your real self infront of someone. I think it doesn't becuase many people can be good and nice to your "mask" but in the long run we all have masks and don't know who to be in this world. People expect you to be something you're not and we try to please a lot of them by being fake.
