Why do we send selfies? And why do people ask for them in return? Is it plain and simply narcissism? A need for validation? Or do we genuinely think that's the best way to let people in on what's going on in our lives and how we're feeling when an emoji just won't do?

"People are using the selfie as a means of claiming ownership of their bodies, identities, and lives."

Walking through Times Square as quickly as possible, I was astonished to see about 1,000 people all clustered and staring up at something. You don't often seen 1,000 people all staring at a single spot. Something big must have been happening. I turned to look. What they were all staring at, what had grabbed their attention, was... themselves.
