Are the people in this thread kidding?? I wish my childhood bullies would send me an "I realize I was a jerk, sorry" letter. I would respond to say "Thanks" and to put the past behind us. Would probably not build a friendship with him, trust doesn't flip 180 degrees like that, but everyone makes mistakes, and some realize those mistakes over time and feel sorry about wronging others. So, that would boost my impression of him, and enable me to give him more benefit of the doubt where I hadn't before.
