No, three years is not enough time.
I am so glad the last words we spoke to one another were, "I love you, Sissy." and you said, "I love you, too." I can still hear your words, your inflection, echoing in my head, echoing in my heart.
This is the fourth birthday of yours that I cannot wish you a year of Happiness. I miss our shared history. I miss knowing you are in this world. I miss you, Sissy.
