I'm sorry to hear how your daugher has been treated by her birth mother, but am so glad she has you in her life. Shunning someone who isn't even baptized? How on earth does that woman think such actions would endear her to her daughter? How could such a thing entice someone to embrace dubdom?
They don't get it - emotionally in the deep-freeze, living sterile, cold lives - glad I'm out and that you are too.
Congratulate your daughter on her graduation for us!
