I guess in our lives, while we’re deluded by the fact that we’re alive, we’re actually rarely “alive”. We’re mostly scurrying through, in our bubbles, clouded with expectations, fears. Life, just by being aware of our aliveness, can be an overwhelming experience.
I think we share pics not only to impress, but to express. The teenage girl may be exploring their femininity, the woman may be feeling like herself. I guess we can just be appreciative in that case and not assume any indications :x
