Admit this. There are some wounds that will just never heal. It can be gently dusted by other things in life, but will resurface even with the lightest touch. To remind you of the conflicts that can never resolved, accuse that can never be explained, misunderstandings that can never be understood. Even between the closest of friends. Or those you deemed as close friends. You can never forgive. You may forget, but the memory will not be lost forever. The scar will burst open suddenly, in the middle of the night, slicing every cell of your body, flooding you with depression, left you in doubt with the genuineness of friendship, no matter how strong it seems to have forged.
These wounds will just be left opened.
