There is this man who moved from apartment to apartment every few months. We can call him a serial drifter who always seemed to be around right after a neighbor fell victim to burglary. This man had been caught with a history of robbing people, then consoling them of their loss like a concerned neighbor. In one instance, he gave a neighbor a ride to the airport, then proceeded straight to the apartment he knew would be vacant and cleaned it of valuables. When the man returned from his trip to discover the robbery, the neighborly thief arrived to express his shock, disbelief, and sorrow at his victim's loss and expressed his hope that whomever did such a dastardly deed would be caught and given the punishment he deserved.
Be careful what you wish for--the man was finally caught in the act and got the punishment he deserved: a few years of down time in a penitentiary.
Sometimes enemies are closer than friends!
