To Forgive or to Forget?!

To forgive your friends or to forget them? That is the question.
In a world where everybody is ready to trip you if you look or feel better than you are suppose to do, which strategy is better: to forgive your friends for their wrongdoing or to forget them altogether?
So far in my not so very long life I have done both. And I still cannot decide which one is better. I have even tried to forget and forgive the bad things.
Now I am at a place in my life that I am starting to understand that while one cannot live alone, one does not really have friends.
People do not have morals anymore, they do not respect themselves enough to respect others. They mock each - other's way of talking, walking, dressing, thinking.
I think we live in a world of  connected loneliness and self-disrespect and that anyone that does not qualify on those conditions, has almost no chances of survival, at least not in this type of oneself. We just take so many blows to our self-esteem and morals that we start to change unwillingly. Terry Pratchett wrote: "History has a habit of changing the people who think they are changing it." I will paraphrase that : Society has a habit of changing the people who think they are changing it for the good.

So let me ask you one more time. Do you Forgive or do you Forget?
