Selfies - Are they necessary?!

Mirror mirror on the wall, who's the prettiest of them all? Take a brief look at yourself now at a mirror and ask yourself do you look nice? Would you post a selfie of yourself to your friends?
This observance has become a viral obsession to some girls and guys on social media.
A selfie is defined as a type of self-portrait photograph, typically taken with a hand-held digital camera ot camera phone. (text taken from: http://en.wikipedia.org/wiki/Selfies). Check some of the craziest selfies here:

What I love about selfies is that people can get creative and express their individuality to their family, friends or to anyone they like. 

But what I hate about selfies the most, are those people who has posted many selfies of themselves constantly, like they don' t have a life!

So what do you think?!
