This man has called me several times, saying he wants to get to know me.  Within three days of when he first contacted me, another man with same first name, different last name, did same this.  this has never happened to me before and I am not on any dating sites and am not interesting in that sort of things.  I am a widow with a new job and am happy by myself.  I confronted one of them and he said "HE HEARD ME" and dropped it immediately but the similarities in these two people is uncanny.  Plus this is a Washington DC area code, says he lives in Miami.  Should I be worried?
