My 85 year old mother knows that I live as a woman and is more than fine with it which is a testament to how far she has come. Of course, I have educated her over the years and she has progressed to a point where she disowns many of the ideas she once held. Having 3 of her grandchildren plus her eldest child be members of the LGBTQ community certainly has helped in that regard.
It's funny how even well into adulthood the opinion of our parents still holds sway over us although I would not change my life were she not approving. Still, it speaks to the inner child and how the psyche has been forged throughout our childhood and into adolescence.
Her approval is also a bonus that at one time I dare not count on, but am now glad I can find satisfaction in.
