...an element of cool is to both be calm in your environment and
attentive to what non-verbal cues are taking place around you....then
you act on the non-verbal cues and the recipient...while both flattered
and also sometimes surprised makes you the center of attention for
a moment as they come to this realization yet you continue to remain
calm and settled during the attention and are thus labelled "cool" not
only for not getting excited about oneself but by paying attention to
others and yet somehow aloof from the activity itself...this is "coolness"...
