I am a photographer first and foremost. But I am also a people observer with an uncanny knack of pegging people right off the bat. I can tell you usually within the first few glances, with nary a word if you and I will hit it off. Now this doesn't mean I'm a judgemental man; far from it.
In any case, this young woman struck me as someone not quite trusting of many, especially strangers yet adventurous whilst cautious and aware of her surroundings. Not only is she fit from keeping an active lifestyle (hence the wheled skids on her feet), she is also aware of her surroundings and cautious all at the same time (noting the forethought of carrying her car keys on her sakte around a public park -- key held like a dagger to fend off attackers).
It is unfortunate that beautiful ladies have to think this way yet it is something we must all think about. Oh how I long for a more innocent time where such sights were beheld instead of being eaten by the "big bad wolf.."
