To Forgive is To Forget, Really?

                   People say that to forgive is to forget but I dont really believe this saying. For me, there are some things which are not supposed to be forgotten. Mistakes, these are what we should be learning from. Then, if we will just forget every mistake we have, how would we be able to learn from them? I think that we should remember these mistakes and make the best out of them.
                   Personally, I have experiences that forgiveness does not mean forgetting something. You can easily forget something and then time will come and you would remember the mistakes of other people. When these times come, you might just believe me.
