Pictures Taking Alone! Why?


Before people spend their most of the time looking at the mirror but along with the improvement in technology people spend their time taking their own pictures. so here is the question. Why do people take their picture's themselves? I guess they take pictures of them selves posing because they love them selves (: or maybe they believe that  they can take a better picture of themselves than someone else could but in my view I think its really weird especially for an adult to do take random pictures like a teenager.
