thinking about reconciliation

I'm "leading" faith-sharing group this coming Tuesday and was feeling at a loss for a topic. (I am comforted that we can always fall back on the slips of paper with questions on them that we generated.) A bunch of stuff today (including #LoveOnTrial.org) got me thinking about the issue of forgiveness, though, and at the idea that I have NO idea how to talk about forgiveness, the idea of reconciliation came to me (that one especially because of LoveOnTrial, I think). Would still like some resources to prep with, though.
