Girls take 10-20 pictures, pick the “best” picture, showing they are happy and put together, and then post that picture, often on Instagram. As other girls read the post, they believe that all that is really going on in the peer’s life is great stuff. Girls do not post bad things as a rule! If a boy drinks too much at college, he is likely to post the picture of his vomit. Not so with girls! So, the more time a girl spends on the internet, the more her picture of reality is unreal and she is likely to get very depressed and think her life if worse than her peers.
