The other day I was listening to the radio and they were talking about the idea of writing a letter to someone who you felt had wronged you who you just couldn't quite seem to "forgive and forget". A letter listing your feelings, thoughts, everything that you really wish you could tell that person and then you're supposed to rip it up and throw it away. The twist this time was that the person explaining the exercise said that its not always a one time cure-all. Sometimes you have to write (and destroy) the letter again and again and again before you are finally able to get past it.
My twist on it ... I wish I could write the letter, watch the person read it, then wipe it from their memory so that I wouldn't have to deal with their response. I think that may be a sign that I have deeper issues. ;)
