What's your phone face?

After seeing the photographs in this article I actually felt quite sad. Surely we don't all look like that? I decided I should conduct some research. Although not entirely scientific or a big sample, on my way home from school I looked around on the tube carriage and the vast number of people on their phone. Expressionless people. Are the things we are looking at really that dull? If so, why are we looking at it? Maybe we should just look up and smile and see how that makes us feel for a change? Maybe then we will actually start looking like the selfies we post online?
