Life is full of difficult people. They cut in front of you in traffic, put their trash on your property, accuse you of dishonesty, cut you no slack for being human, and seize upon every opportunity to do something to irritate or demean you.  Some do it unconsciously; others do it deliberately and with malice. They return merchandise which is half worn out, asking for a refund because something doesn’t fit right or was defective. The list of what difficult people do to irritate you is endless.
