It easy to say but difficult to practice it. I hate to say it, but seriously I can't even think about that. Within one year and half, they hurt me so much with those saying and actions, and then after 2,3 months after that, they simply come to me and say, "Hey, I'm sorry!".
It's not easy to forgive and forget. You have thrown your shit on my face, I even cleaned up your shit, in physically no more shit on my face, but the smell is still there. So, it is totally hard for me to FORGIVE you for shitting on my face and to FORGET your smelly shit.
