This essay "My Impossible Father" on Bilerico Project written by a young son talking about his transgender MTF father. Jillian T. Weiss posted it in honor of the day.
I love his description of transition along with his father.
I imagine this passage resonates with anyone who has witnessed the transition of a parent, or any loved one. We need to share our stories.We both underwent changes in our time apart; I sprouted into adolescence while she transformed into a woman. Each time I saw her she had transformed more and more into a woman. By the time I was ten years old, and began to understand the world, my father was comfortably a woman, and I was comfortable with her as a woman.
My relationship with my father has molded me to who I am today. The lessons I draw from my father include those about gender, but largely influence my life in ways only a father can. I learned tolerance, patience, and acceptance from my father's transformation but more importantly she instilled in me a fundamental tolerance for the unknown as well as vigorous passion to find that which I love, not that which provides momentary satisfaction.
