As a gal, if i am intro to a guy, i will try to shake with my
fingers only, and if the guy show sign of grabbing my whole hand, i
will not talk to him anymore, just smile and walk away, cos it give
me the creep that he is a womaniser.
And i also try to shake with their left hand, cos i know
many/most guys use their right hands to shake other
things...eeeeee...no wash one...
but if he's a business guy, he would grab your whole hand and shake
warmly to show sincerity.
