Shake & Smile
Some people may smile at you and shake your hand while their hearts are as dark as Erebus, as Shakespeare says in the Merchant of Venice:
"The man that hath no music in himself, Nor is not moved with concord of sweet sounds, Is fit for treasons, stratagems, and spoils; The motions of his spirit are dull as night, And his affections dark as Erebus. Let no such man be trusted."
So, do not be fooled by hand shakes and big smiles. How people deal with each other is the criteria here.
