Somehow related, I had to go through my father in-law papers after his death, and I have seen papers that probably were not meant to be seen ever. I am now part of this secret. The weird part is that I feel that I cannot talk about it to anyone in the universe. For the first time in my life, I feel the burden of keeping secret until I die. There is no therapy for it. Now, I understand how some people when tragedy strikes, have to bury it deep, to the point where they forget about it, as it is too painful to even think of it. I am at a point where I do not want to impair (drunk, high) myself and reveal the secret. I thought my life was simple, but man some unfortunate events can flip entire lives... I was a firm believer that talking the truth/facts was the best solution, and now I realize that some things better stay buried as it would generate more pain than anything.
So, some papers might not be good to keep, as you never know what it could unleash after you pass away (and that can happen anytime).
