Thanks for the links B. Interesting to read differing views.
There's a saying that says 'every picture tells a story'. Well, it depends upon what one sees. Perhaps some see selfies as a narcissistic, armchair led and lazy way of promoting fund raising. It can also be fun.
So what lies behind the bare face. I have a friend. A young mother with two teenage children, a husband with inoperable spinal cancer. She is an upbeat, funny and outgoing young woman, who involves herself in raising funds for cancer research. Just does it. Doesn't bang on about it. She posted a selfie on fb. I don't have a problem with that. The picture itself isn't brave, but how she lives her life is.
