I just have to comment on selfies. Many people take selfies because when they go places there is no one to take a pic of them but themselves, or other people take bad pictures or get annoyed being asked to take a picture. When we travel and take selfies of us doing things because we want a pic together but there is no one with us to take a picture. Or other people have horrible photo taking skills. We’d rather not have heads chopped off lol

I don’t believe selfies have any link to narcissism. It’s just a convenient phone feature. I don’t see what’s the big deal. And I am not millennial. Lol I am in my 50s. My dad takes selfies and he is in his 80s. It’s just basic tech feature
