Real Life VS. Internet Personas

I was looking at my friends Instagram accounts, and I noticed that most of them act like a different person then the way they act to my face. It's like they aren't afraid to be mean online, but when they are in front of you, they are competely a different person. On instagram, they take selfies of things that you wouldn't expect. They post commments that could bring a tear to your eye. They are not themselves, and I think that is happening to many people. If you agree with me, please leave a comment below expressing your thoughts.
