Forgiving frees us, gives us peace, we close a cycle and continue. It is true what you say, we waste time not turning the page, of course there are situations that are hard to forgive but I feel that for our peace of mind we try to move forward, not forgetting but continuing and leaving everything in God's hands, not taking justice in our own hands or anything like that, not revenge.
Let's remember that we are an example to the little ones, a pleasure to read, good narration.
