I felt very guilty and in denial for my Dad's passing. There were lots of times that I saw him coughing and didn't know it was serious. I could have saved him before his condition gotten worse. I shouldn't let him go to the doctor by himself! He's a long time smoker and I should have known but now it's too late.

Why didn't I see it? I've been blinded! It's a punishment for me. My dad never ask anything from me. He was a very kind and gentle person. He always smile and did not complain about anything.

Am so sorry dad! It's too late!
