You shake man han',  you no shake him heart.

__Bahamian proverb

Let's simply be cautious in our dealings with others, trust our intuition if it seems to be generally on target, and accept that a handshake is an act of civility and not love.  People will hack their way into your life and leave a trail of morsels to let you know they have stolen your security like spooks in the night.  Thankfully, there is sincerity and friendship and romane in the world that can be ours if we are receptive to it.
