forgive and forget?

As i have become older i am learning that humans struggle to forgive and even more than that they struggle to forget.  Recently i have irritated a young friend of mine by stepping in when i shouldnt have.  I had good intentions, and i thought i was doing the right thing... but in the long run it came across decetful and rude.  So, once i realized i was wrong... i went to step two... forgiveness.  I have asked for forgiveness of the Lord and my young friend.  I know my God has forgiven me, but i do not believe my friend really has done so yet.  She hardly will speak to me... i am not sure that once she does forgive she will ever forget.  As a science teacher i am in awe of the capacity of the human brain.  The fact that it works all day long making sure our heart beats and our lungs expand it amazing!  The things that we can recall from years back are awesome at the least! Yet sometimes this leads us to things we cannot forget.  I pray daily that my friend will forget and allow us to reconcile our friendship again.
