My father died when I was 11 & I always wanted to know more about him. I never got the time to get to know him as I would have liked to. I wish he had thought in advance to write down things for me & to reassure me that he loved me. I am now a grown woman with a family of my own & I most definitely what my children & grandchildren to know things about me & how much I love them.
I was raised by my Dad, there are certain times I wish I could have had one last message from him. I was in the military and my Dad wrote a letter to me everyday while I was in basic training. I cherished those letters. He passed without telling his side of a story and another family member shared information with me, that probably should have come from him. I believe it was too uncomfortable for him to elaborate on it.
I hear people around holidays say “I miss “ someone special. I think a letter from that special person in their own handwriting would provide much comfort. I really feel in my heart that one last letter can provide comfort and be cherished from then on. I personally want to leave a letter to be delivered to my son on his birthday month letting him know he truly was a real joy to me. I know I will be on his mind and I will reassure everything is OK.
