Praying for people who drive you crazy

"How many of us have conflicts with someone else- and how many of us pray for that person? We have individuals with whom we are competitive, or whom we dislike or have a quarrel with; but very few of us have true enemies in the martial sense. And yet if Lincoln could pray fervently- and contemporary reports indicate he did- for the people who were opposing him, how much more can we do for someone we just find a little irritating?" 
— John Wooden (A Game Plan for Life: The Power of Mentoring)
