A selfie is a picture that someone takes of themselves, physically.

People take selfies for fun, or to keep as memories, or to make themselves look good. They use selfies to get comments and likes, and to promote themselves. Some people (not all)  who take selfies take them to get attention, or to be flattered, and others just take them for the pure fun of it. I think that if someone takes too much selfies, they are confident and like to take and see pictures of themselves. If people never take selfies, i don't trust them, because like James Franco, i feel like they have something to hide if they don't show their face but sees pictures of yours. The most interesting thing about a selfie is the background, and they expressions they make.
