I dont know, i never really look for anything ,but there is usually an aura or vibe that tells me whether they are to be trusted or not.
whether theyre a nice person or not
If I'm not close, their overall shape. As I get closer, if they have a nice face, are well kept. If they're a woman, do they have a nice figure.
their eyes. And how they react to looking you in the eyes.
Nice teeth and smile
in women the eyes love the eyes
her eyes, then her smile...
